how can i determine which stores are regarded as supermarkets for a rewards credit card?
user
each company that has an account with the credit card network has to classify themselves as a particular type of business.  the credit card company uses that classification to catagorize the transaction on your statement. if you buy a t-shirt at a grocery, amusement park, gas station, or resturant; the transaction will be labeled by the vendor type.  look at recent credit card statements, even if they are from different cards, to see how the stores you want to know about are classified.
