Cartunda by Dovydas Rimeisis

Cartunda is a tool for group purchases — several people ordering together from one shop, one person placing the order.

This extension does the two jobs a browser is needed for.

Adding what you find. On a shop you've allowed, a small Cartunda button appears on product pages. Press it and the item - title, price, currency, variant - goes into the purchase you choose. The button also shows what's already in that purchase, so you can check quantities or remove something without leaving the shop.

Filling the basket. If you're the organiser, the extension puts everything everyone ordered into the shop's own basket for you, one item at a time, and then reads the basket back to confirm what actually went in. It reports what arrived, what went in short, and what the shop refused — because an add that silently does nothing is the normal failure, not the exception. It stops at the filled basket. You review it and check out yourself.

It knows how to order from Shopify, WooCommerce, PrestaShop, IdoSell and Magento shops directly. For anything else it uses the shop's own add-to-cart button, which an administrator can point it at once.

What it doesn't do

• It reads a page only when you press its button, never as you browse.
• It has no access to any website until you grant it, one shop at a time, and you can withdraw that at any time in your browser settings.
• It never learns your password for a shop, never enters payment details, and never completes a purchase.
• No analytics, no tracking, no data sold or shared.

Requires a Cartunda account. Set the address of your Cartunda instance in the extension and connect it once.
