I'm considering a Costco card. I got an email from them the other day and you get 4% cash back on gas purchases and since they average $.20 per gallon cheaper than any where else, that is where I fill up.
It's a racket for sure but wth.
My wife and I use the Costco card and like it especially for the gas discount. It gets paid off every month via the phone/bank acct.
Works great We also use the NEA Visa Card but it doesn't pay back in cash, but it works good for Airline flights etc.
I had a Cabela's, and abused it---don't have it anymore
