A one time email is fine.

However, I am in Canada. So can only test it once you expand there. Thanks.

I don't know how things are in the US, but it does seem like the grocery store oligopoly is squeezing consumers a lot, so tools like this are valuable for injecting competition into the system.

Shameless plug for my own project (https://grocerytracker.ca/) since you're in Canada. Eventually I'd love for it to do what you're suggesting, but for now the closest thing you can do is create a basket for each store with the same items and then check each week to see which is the cheapest.
