My capital one CASH credit card has a full 1% cash-back with no limit (unlike the other guys that offer 3% but max-out at $12 a month), plus I get 25% annual bonus on the cash-back I accumalated that year.

Capital One has no foreign transaction fee if i travel. The other guys charge 3% on EVERY transaction.

My Capital One CASH Visa card is also excellent for fighting unauthorized charges against Pay Pal / eBay if you ever need to reverse a charge (God help you if you have Discover card)
Discover card claims to give 1% cash-back, but that's only after you spend around $5000 in one year, then anything over that $5000 is 1% cash-back; however, the "clock" resets every year and yo uwon't get 1% cash-back the following year until yo uspend that $5,000.

Discover really only gives 0.25% cash-back.

This is why Capital One rocks.

maybe the site on my signature could help you.

good luck!

I am not a big fan of discover card. Hav had some issues in the past.
