Online grocer Puns

I am trying to find out which stores will qualify for the cashback. As I understand, as long as the purchase is not defined as a superstore, but for Amazon (Fresh/WholeFoods) and stores like Trader Joe's/StarMarket,... Do they qualify?
Would love to hear your experience, or how to find out whether certain places qualify (especially online grocer, since the Visa supplier locator platform only work with physical locations)

Cheap German mustard is so much better than any mass produced yellow mustard in the US. It's obviously great for brats, sausages and Cubans but also improves deviled eggs and dishes like tuna salad. You can also choose different levels of spiciness aka "scharf." Squeezing it out of a metal tube adds to the enjoyment not to mention the tube helps with plugging and separating. If you have an international grocery or want to search online you can find many different types there.
