AMEX & Twitter Team Up
 

"Amex and Twitter partnered up and launched @AmexSync Account (a Syncard campaign) five days ago. The Syncard is a greener way to super coupon; it allows American Express Card carriers to sync their card with Twitter, tweet with special hashtags to claim the offer, and save big when they make certain purchases on store or online with their synced Card."

While they are referring to this as a form of Mobile coupon I see it more as a Membership Benefit Discount.

"Over millions of digital coupons have been claimed in the past days, in fact, the Syncard campaign has been so successful that partners like McDonalds and Whole Foods have decided to increase their cap offerings to meet demands."

Gee! You mean Mobile coupons ACTUALLY Work? Who woulda thought! lol
