A gotcha on the Amazon Store Card. Make sure your defaults are set for 5% in all cases and keep an eagle eye out for anyone else using your card.
My husband was gypped recently on a couple of large purchases when he used my card. I have my defaults always set to 5% statement credit, but because he is not the prime account owner or store card holder, he doesn't have a place to do this.
He made two large purchases (>$149) recently, and didn't realize in the Amazon payment screen that "Promotional Deferred Interest" had been chosen for him by default. So he accidentally forfeited the 5% store credit for those purchases. This is infuriating, because he didn't even realize what was happening. And it just seems so sneaky. It's not even apparent on the checkout page that it can be changed.
I have the correct defaults set in my account, but he didn't have the option to set the same defaults in his, since he is not the card holder.
We did a test with a higher dollar purchase, and found that if you go to "change payment method", then you are given the opportunity, under the store card, to choose between 5% statement credit or the promotional financing.
So - be sure when using this card for purchases over $149, that "promotional financing" is not selected by default, and use "change payment method" to correct it so that 5% statement credit is selected instead.
Turns out my husband had been caught out by this a year ago as well. Poor thing - he had no idea what had happened, that there was some alternative to the credit (not desired by us) for larger purchases, and I just caught it on this recent statement.
He provided feedback to Amazon on their user interface, they called us to discuss it, and they linked us to Synchrony bank who they said could change it from promotional financing back to statement credit. Synchrony bank customer service readily submitted the change request to store credit from promotional financing, that I should see something online within 48 to 72 hours, and that it might take one to two statement cycles to get the credit. So - if you catch it quickly Synchrony can change it - but what a pain!!!
