I agree that this would be the ultimate tool for consumers, but think how hard if a problem this is. Do you track the price for every grocery store in the world. Where does that data come from?
I think for starters that receipts should be provided in a format that's useful for consumers. Consumers could then contribute to keeping this database up to date. There is absolutely no consistency in the way stores print receipts and I'm pretty sure that's by design.
The way business work is they want to be able to track you without you being able to track them.
- owenversteeg 7y agoIt's already a collaborative database using tons of user supplied data. How hard would it be to add another entry for (price, date, supermarket, location)? For example (€4.99, 25/3/19, Lidl, Berlin DE) There's already an app with a scanner, you could just walk down the supermarket and scan a few things and when you do you see the price displayed for your location (if available), if it's significantly different you can change it.
- prewett 7y agoI don't think price would be very meaningful, since the price will be dependent on area. A major metropolitan area with a high cost of living will have higher prices, as will a small town that's 30 minutes from the nearest small city. And across countries, not only is there different tax rates, whether the tax is included in the price (US: no, Europe: yes, I believe), there is also the variation in exchange rate, which could be substantial. Then some stores may use the product as a loss leader, while others do not.
