You don't give them any CC information. Ebates can be flaky at times, since they leave a window of up to 30 days before you can get credited. Your just left in the dark during that time. Sometimes you can fight it if you save your information and they will credit you manually. I've gotten one check so far from them for 15 dollars. Hey money is money right? What you got to lose
just make sure you shop through their referral link tho.
