This really hurts those of us that are unable to access these types of reward points. It pushes additional costs onto us all, but especially onto those without exceptional credit.
Someone taught me long ago that if you're using a debit card in a store you actually like, you should chose the debit option rather than the credit option, as the fees are lower.
I sometimes do the reverse when I'm in a shop that I don't have good things to say about, especially if I think they just cheated me in some legally defensible way. Like Captain Ahab trying to kill the whale with his pocket knife. Fuck you, I'm taking 1.5% of your life away!
