Mastercard has a holiday offer going where if you register your Mastercard credit card number and spend $200 online with it, you’ll get a $20 gift card. Valid for first 80,000 – this promo started yesterday and I have no idea how long that’ll last, so just treat this like a nice surprise if it comes.
* Starts 11/15/11. Ends 12/31/11 or while supplies last. Offline, PIN-based & international transactions ineligible. Gift Card quantities are limited to the first 80,000 eligible entrants & maximum 10,000 other gifts to next 10,000 eligible entrants.
