I'm still thoroughly annoyed that retailers don't let you easily access receipts in a programatic way. Many allow you to look at them online, if you have some form of loyalty card, but you can't just scan a barcode or punch in a number to get it anonymously.

Not least because it would simplify apps like this.

Granted, I may be a special case as someone who still has every receipt from the past ten years.

I agree. Hopefully there will be a day where grocery retailers provide access to their product data APIs to make this a smoother process. Or if the store provided a QR code on the receipt so you could quickly see information similar to what's on GroceryTrip.
