HT - Friend via text message.
Last Sunday, I mentioned that it should be possible to buy a $50 Mastercard gift card with 2 American Express gift cards enrolled in the Sam's Club $20 off $20 online offer. The $50 Mastercard would essentially be 75% off.
Doctor of Credit already mentioned that $20 credits have posted for 3rd party gift cards , but I haven't seen anything for $50 Mastercard gift cards.
Nowhere in the terms and conditions did it forbid a gift card purchase.
I haven't had a chance to buy the gift until yesterday (more on that soon) so I don't have my results yet, but a trusted friend bought the $50 Mastercard on my recommendation and the credits posted to his account! Phew, I would have had a lot of explaining to do otherwise.
Here is a picture from his account, as you can see it took 2 days for the $20 credit to post:
