A discount table for lavka.yandex.ru: biggest discounts first, filters, price history, price watching and adding to cart right from the table. Everything stays in your browser. Unofficial, not affiliated with Yandex.

It is not endorsed or supported by Yandex. "Yandex Lavka" and "Yandex Pay" are mentioned only to identify the website this extension works with.

The extension shows what the website already sends to your own browser tab. Prices and discounts in the table are for reference only; the final price is the one in the website's cart. The extension may stop working if the website changes. You remain bound by the website's terms of use. Provided free of charge, "as is", without warranty of any kind (MIT License).

Where it works

Only on lavka.yandex.ru (Yandex Lavka, a grocery delivery service in Russia), in a tab where you are already signed in. The catalog is visible without signing in; the cart and the Purchased view need an account.

The interface is in Russian.

What it does

• Shows the products in its own table sorted by discount size, largest first. Any column can be sorted: discount in percent and in rubles, price, price per kg, l or item.
• Filters: search by name, minimum discount, minimum saving, price range, categories and subcategories, hide categories you never need, best discounts within a shelf.
• Price history for every product and a "vs. 30-day low" column.
• "vs. shelf": cheaper or more expensive than usual for this shelf, per kg, l or item.
• "New": what got cheaper or appeared since the last catalog update, or within the last N hours.
• Watchlist: star a product and the table shows when it gets cheaper.
• "+" and "−" buttons put a product straight into the website's cart.
• Purchased: what you have bought before, with today's prices.
• Prices with or without Yandex Pay, whichever way you pay.
• A reminder to update the catalog (after 2 hours by default, silent at night). It never updates the catalog by itself.
• CSV export, backup to a file, light and dark theme.

Getting started

1. Choose a delivery address on the website and open any category, so the extension learns your store.
2. Open the panel with the rat button in the bottom-right corner, the toolbar icon or Alt+Shift+D.
3. Press "Обновить каталог" (Update catalog): 2–3 minutes, you can leave the tab alone.

Products you browse on the website get into the table by themselves.

What it does not do

• It does not send your data to the developer or anyone else: no servers, no analytics, no ads. Requests go only to the website itself, from your tab, and to its product picture server.
• It does not update the catalog by itself: only when you press the button, and the full catalog at most once an hour.
• If the website asks to wait or to pass a "not a robot" check, the update stops and waits.
• It does not run in private windows.

Firefox for desktop, version 140 or newer.
