I signed up for this card because of their great sign up bonus, $30 of any amazon purchase, with it I got a free set of pans! I didn't think I'd use it much after that however I was pleasantly surprised how easy it made check out in Amazon. Amazon remembered my card info, cutting down valuable time! The rewards are great and come fast! I've only had to call customer service once, lady was pleasant and eager to help. Great automated system to check balance and payment status, no need to give your information a dozen times! The only thing I don't like is the high interest rate, I recommend paying off the balance each month or you will be paying a lot in interest. Overall a great card I have no problem using anywhere, anytime!
