Version 1.1.139
Released Sep 23, 2026 - 357.46 KBWorks with firefox 109.0 and laterWhat's new in 1.1.139
Vinted listings are easier to finish yourself. From Sell The Flip, open Vinted's create-a-listing page with the title, price, and details already filled in.
Your photos show on that page so you can drag them into Vinted's photo box, then hit List.
When Vinted says the item is listed, we bring you back to Sell The Flip and link the listing. You should not need to paste the link.

Version 1.1.138
Released Sep 22, 2026 - 342.08 KBWorks with firefox 109.0 and laterWhat's new in 1.1.138
• Vinted: if a category needs a color and the listing color is blank, we now read it from the title (for example a Sage bag or Black sunglasses) instead of failing after the photos go up.
• Vinted: when Vinted asks for the item's measurements, we send the listing's package length and width. If those fields are empty, you'll see a clear prompt to fill Package dimensions.
• Depop: a saved address with no usable phone no longer blocks the post. We ship that one on your own, and if Depop still needs a phone update we tell you to fix the address on depop.com.
• Delist: a Poshmark listing that already sold, or is already gone, now counts as done instead of showing as a failed delist.

Version 1.1.137
Released Sep 21, 2026 - 341.17 KBWorks with firefox 109.0 and laterWhat's new in 1.1.137
Sync All and Sync on a single listing can now bring photos over from Poshmark, Mercari, Depop, Facebook Marketplace, Whatnot, and Grailed when that item has no photos in Sell The Flip. Listings that already have photos are left alone.
On Facebook, Sync also fills blank category, brand, color, and condition from the live listing.

Version 1.1.136
Released Sep 20, 2026 - 340.18 KBWorks with firefox 109.0 and laterWhat's new in 1.1.136
Mercari posts no longer fail when the title is empty or over 100 characters. We fill in a usable name so the listing can go up.
Whatnot closet and order checks skip a path that never worked, and if Whatnot is blocking your account we wait about 30 minutes instead of retrying over and over.
Depop sold items and photos that arrive as links now sync instead of failing the import.
Whatnot and OfferUp order sync skip cleanly when you are not logged in or do not have a normal browser window, instead of showing a failed sync.

Version 1.1.135
Released Sep 19, 2026 - 338.57 KBWorks with firefox 109.0 and laterWhat's new in 1.1.135
OfferUp now tells you in plain words when a category has used up its free monthly listings, so you can buy the extra post in the OfferUp app instead of seeing a generic fail. If you are not signed in to OfferUp, you get a sign-in message instead of a timeout.
Poshmark posts now follow Availability. Pick Not for sale on the listing and the closet item stays not for sale.
Sold-item sync is sturdier. One odd OfferUp or Facebook sale no longer stops the rest of the batch from coming in.

Version 1.1.134
Released Sep 18, 2026 - 337.06 KBWorks with firefox 109.0 and laterWhat's new in 1.1.134
OfferUp posting is more reliable. We now match OfferUp's own post flow for category and location before the listing is created, so posts that failed with a generic error should go through.
You can still post local pickup listings, import the items you already have listed, and take them down from Listings or the listing editor. Sign in at offerup.com in the same browser, then pick OfferUp on Connections when you post or import.

Version 1.1.133
Released Sep 18, 2026 - 335.94 KBWorks with firefox 109.0 and laterWhat's new in 1.1.133
OfferUp is now a full marketplace in Sell The Flip. You can post local pickup listings, import the items you already have listed, and take them down from Listings or the listing editor.
When you post, we fill the title, photos, price, category, and condition. Import brings in your current listed items (not sold ones). If an item is already archived on OfferUp, we treat it as already down instead of showing an error.
Sold OfferUp items show up on Insights with your other marketplaces. Local pickup sales have no seller fees.
To start, sign in at offerup.com in the same browser as this extension, then open Connections and pick OfferUp when you post or import.

Vinted posting no longer fails on categories that already offer Small, Medium, or Large. We were sending extra item measurements those listings do not need, and Vinted turned the post down. Update the extension, then try that listing again.

Version 1.1.131
Released Sep 17, 2026 - 323.08 KBWorks with firefox 109.0 and laterWhat's new in 1.1.131
• Vinted import still works if you have been logged in on vinted.com for a while. Open Connections or Import and pull your closet as usual.
• Mercari now accepts titles and descriptions that include emoji or decorative symbols. Those characters are removed so the listing can still go up.
• Poshmark sync finds listings that used to be skipped on a small refresh. Sync All and a single-closet sync still do not post or change anything on Poshmark.
• If a Poshmark item is already sold, delist now finishes cleanly in Sell The Flip instead of looking like a failure.
• If Whatnot rejects a photo, the message now says it is their community guidelines check. Try the same photos on whatnot.com if you need to confirm.
• Scheduled Facebook posts keep your Hide from friends setting. The default stays hidden unless you turned that off in Listing defaults.

Facebook Marketplace posts that were failing with "Your Request Couldn't Be Processed" should go through again. Sign in to facebook.com in the same browser, then post one listing to Facebook from Sell The Flip.

Whatnot posts that need a backup category now use a working Other category instead of one Whatnot no longer has. That stops the same Whatnot error from repeating and then blocking the post.
Posting, import, and fill on the other marketplaces work the same as the previous store version.

• Depop: posting a new listing no longer sits on "Creating listing" with no error. Keep depop.com open and signed in in the same browser, then post one listing from Sell The Flip.
• Facebook: syncing several listings at once now finishes instead of dying mid-run on Facebook. Select the rows on Listings, hit Sync, and each Facebook listing is read on its own.
• Poshmark: importing a closet now brings the SKU / closet code into Sell The Flip with the listing.

Version 1.1.121
Released Sep 12, 2026 - 314.49 KBWorks with firefox 109.0 and laterWhat's new in 1.1.121
Facebook Marketplace posting is more reliable. We now pick up your Marketplace location from facebook.com, so new listings are less likely to fail with a blank "Your Request Couldn't Be Processed" message.
If Facebook still refuses a post, we tell you to try the same item by hand at facebook.com/marketplace/create/item first. We only mention switching off a Page or professional profile when that is actually the issue.
Sync with Facebook should no longer sit silent until the site says the extension did not respond. You will see progress while we connect and read your listings, and a clearer message if Facebook stops mid-sync.
Stay signed in to facebook.com in the same browser (personal profile) when you post or sync.

• Whatnot posts that failed because Chrome withheld site access now have a clear fix: use “Grant site access now” on the posting screen, or open the Sell The Flip toolbar icon and grant marketplace access.
• Vinted import is more reliable when you are already signed in at vinted.com. Open Import, choose Vinted, and your closet should load instead of getting stuck on a sign-in error.
• Photo uploads are more reliable on Mercari, Depop, Facebook Marketplace, Grailed, and Whatnot, including photos already saved in Sell The Flip.

Version 1.1.119

• Vinted books: a 10-digit ISBN from an older book is accepted, not only the 13-digit barcode number. Put it in the listing's SKU field.
• Depop: a shop that has sold items before no longer gets stuck even if nothing is for sale right now. If you have never listed on Depop, we tell you to finish Depop's first-time Sell setup (including Payments) before posting.
• Clearer errors when a post or delist fails. You see a short message instead of a wall of page text. Poshmark already-sold delists and mixed eBay photo problems are called out in plain words.

Version 1.1.118
Released Sep 9, 2026 - 310.58 KBWorks with firefox 109.0 and laterWhat's new in 1.1.118
Posting and delist errors now show a short, readable sentence. You should no longer see a wall of code, HTML, or JSON when something fails.
If your Depop shop is not set up yet, posting to Depop stops right away and tells you to finish setup on Depop, instead of sitting there with no answer.
If you delist a Poshmark item that already sold there, we just clear it in Sell The Flip. You will not get a "may not delete a listing that has been sold" error.
If Facebook needs you to sign in again, we say that plainly so you can open facebook.com and retry.

Opening a listing that is already live on Vinted no longer pops extra Vinted windows just to load sizes and category fields. The sizes you already picked stay on the form. Click the Vinted size field, or change the category, when you need a fresh list from Vinted.

Version 1.1.116
Released Sep 8, 2026 - 308.59 KBWorks with firefox 109.0 and laterWhat's new in 1.1.116
Listings you import from Vinted can now post to your other stores with their photos. After you imported from Vinted, posting that same item to Poshmark, Mercari, Depop, or Whatnot could fail on every photo and ask you to reload the extension. The photos on the listing were fine. This update lets those photos upload.
Update the extension, refresh selltheflip.com, then post one Vinted-imported listing to try it.

Version 1.1.115
Released Sep 7, 2026 - 308.52 KBWorks with firefox 109.0 and laterWhat's new in 1.1.115
The toolbar popup no longer asks you to sign in to Sell The Flip. It now lists Poshmark, Mercari, Depop, Facebook, Whatnot, Grailed, and Vinted, and shows whether you are signed in on each site in this browser. Click a row to open that site. eBay still connects in Sell The Flip (use the note in the popup to open Connections).
Facebook imports skip listings that already sold, so they do not come into Sell The Flip as active inventory.
If Mercari needs you to sign in, you get a clear sign-in message instead of a confusing error.
When you run Sync, a sale on a marketplace can show up right away instead of waiting.

Released Sep 6, 2026 - 309.58 KBWorks with firefox 109.0 and laterWhat's new in 1.1.113
Facebook import skips listings that are already sold, so they no longer show up as live inventory in Sell The Flip.
If Mercari blocks a photo upload (usually because you are not signed in, or a popup was blocked), you now get a clear “log in and try again” message instead of a wall of error text.

Vinted is no longer included in Sync or automatic sold-item flags. Vinted treats those automated checks like automated posts, so we leave them off on purpose.
Importing your Vinted closet and taking a Vinted listing down from Sell The Flip still work the same way. When something sells on Vinted, mark it sold on the listing yourself.
Sales Insights no longer pulls Vinted orders. eBay, Poshmark, Mercari, Depop, Grailed, and Facebook sold flags are unchanged.

Safer posting to Vinted
We now leave 5 minutes between Vinted posts (and still cap new ones at 10 a day) so your closet stays in good standing. If you try to post again too soon, we tell you how long to wait, or put it in your Listing Scheduler.
If Vinted pauses listing on your account
We stop sending new Vinted posts and edits until that pause lifts, normally about 24 hours, including taking sold items down. Your other marketplaces keep going.
More Vinted details filled in
Categories that ask for extra answers (for example computers: brand, condition, storage, RAM, charger) now get those fields from your listing, so Vinted is less likely to refuse the post.
To post to Vinted, sign in at vinted.com in the same browser as this add-on, then choose Vinted when you post from selltheflip.com.

Vinted books post correctly
Book listings on Vinted now include the ISBN and the language the book is written in, both of which Vinted requires. Put the ISBN in the listing's SKU field (or anywhere in the title or description). A Book language dropdown appears when Vinted and a Books category are selected; it defaults to English.
Vinted posting stays careful
We still space Vinted posts 2 minutes apart and cap them at 10 per day, so your closet stays in good standing. If you try to post again too soon, we tell you how long to wait.
To post to Vinted, sign in at vinted.com in the same Firefox profile as this add-on, then choose Vinted when you post from selltheflip.com.
