I have a Very Poor (557) score on CreditKarma due to student loans, my Capital One Secured CC, and tons of delinquent balances. While I am working on paying these off, I have had a very impossible time with credit. Amazon gave me a great opportunity! They allow for me to have an $800 Credit Limit [more than enough for what I usually get at any point in time. Just buy one or two things (or xmas shopping), pay off with extra money every check, and repeat].
The only flaw is there is no place that shows me what day the payment will be due, or how much the payment would be. [minimum]
