Originally I was excited to see that kroger had an API, until just about the first thing that the ToS said was "you can't use this for price comparison".

And yea, I imagine dynamic pricing will make things even more complicated.

That being said, that's why this feature isn't built into the billion shopping list apps that are out there. Because it's a pain.

Price comparison should be required by law. In fact, I think it would be interesting for a city to require its major grocers to feed pricing information to a public database.
