Just found out about this exclusive new deals site for Mastercard cardholders, and I wanted to share it with you. Mastercard is offering OOs (aka Overwhelming Offers) at 50% off every day starting at 1:00pm EST! Register now to get in on these savings.
I know many of you don't use credit cards, but this works with Mastercard debit cards as well. And you only have to provide the first 6 digits of your card to register!
