Garbage. Don't Bother.
Used this cr-app three times to transfer funds from Amex gift cards, and it worked ONCE. Checked my precise balance, made sure Amex didn't charge for it on their end, made sure Amazon didn't charge for the transfer (like it fraudulently claims) and it not only failed for no apparent reason 2/3 times, but it gave me the ultra annoying, irremovable red payment error pop-up on my order screen that persisted for days along with the aggravating emails "reminding" me to update my payment method. BIG FAIL, Amazon. Shameful.
