TrackPrices Bot

TrackPrices Bot is the widest price tracker in this list: instead of one marketplace it takes a product link from, in its own words, 95% of online stores, naming Walmart, Myntra, Flipkart, eBay, AliExpress, Snapdeal and Rakuten. You send the link and the bot notifies you when the price drops or when availability changes. Its product page on track-prices.com adds three extras: it points to the same product in other shops so you can compare, it lists coupons and promo codes you can use, and online stores can place a "Track price" button that opens the bot from a product page.

The bot is free for users. The site states that it earns as an Amazon Associate and through other affiliate programs, so expect the store links and recommendations to carry affiliate tags. The bio is written in English and Russian. Support goes through @Help_TrackPricesBot or an email address on the site.

Two cautions. How often prices are rechecked is not published, so a flash sale can pass before the alert arrives. And the company's main site now sells a separate competitor price tool for shops, with the bot on its own page, so watch whether the bot keeps getting attention.
