I am not sure what the credit card storage policies are of Amazon but I am pretty confident, considering their attractiveness to attack, that their security mechanisims are very high and follows all PCI DSS requirements. But more importantly, since I have not opted for auto-renewal on UT doesn't it make more sense to not store that info as an additional security measure? I think Metin's post offers the correct approach.
