I think if your cards are legitmatly bought as new you will be fine. If you buy even a $10 gift card from a reseller you are more likely to be blacklisted than depositing 10k of cards you bought. Amazon does not tolerate fraud and you risk buying stolen cards when buying from a reseller.
I dont over have over 2k but I go thropugh about 20k a year.
