"I bought this for..." app?

Question

Mobile devices

Is there an app where you can scan the bar code, and then enter the price, for how much I bought this box with the bar code. Will someone else scan the same barcode on a supermarket shelf and, based on price history, either buy the item or go somewhere cheaper?

Answer 1

Well, you can write the price in the reviews on https://ratengoods.com .

Answer 2

https://play.google.com/store/apps/details?id=ru.y... - Yandex.Market catalog
Specify key parameters, for example, the screen size for a TV or the maximum load weight for a washing machine - the application itself select suitable models. You can also choose shoes, clothes and accessories for adults and children, specifying the desired size, material, style and other parameters.
You can start using Market on one device and continue from the same place on another. Wishlist items are saved on all your devices after authorization.
