No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
So from October - December I can use my Discover at Walmart and buy a Walmart gift card, collecting my 5% cash back. Then I can use the gift card to get gas, and save 10cents/gallon.
Seems like a lot of trouble, but it might be worth it!
I just noticed this online. I somehow missed this thread. Bumping it up in case I am not the only one who missed it. 15 cents off is about 3.5% off, if gas is $4.25.
lol @ jlu post walmart is so good to us!
