Oh really? I never get any on my cards. Definitely not for things like groceries. Once in a blue moon they have some discounts in the credit card app but they are always discounts based on the RRP price which are totally useless because the same article is cheaper on amazon at street price.

I do have a "credit card" because some sites refuse to accept debit ones. But no cashbacks or anything. Maybe it differs by bank (I use caixabank in Spain)

The one thing I do like as a reward is that caixa funds several museums and you can get in for free if you have an account with them. But it doesn't have to be a credit card, a normal account is enough.
