Plink has rolled out a Facebook Credits-based loyalty program, which rewards Facebook users who dine and make purchases at their favorite restaurants and offline retailers.

In order to gain access to this loyalty program, members will have to join Plink.com via Facebook Connect, register their debit or credit card and start collecting Facebook Credits by dining-out or making purchases at participating national restaurants and offline retailers.

Consumers use Facebook Credits to purchase virtual goods to advance or level-up in popular Facebook games such as CityVille or The Sims Social. In addition, Facebook also allows users to spend Facebook Credits on downloading music, videos or watching television movies.

Currently, Plink's online-to-offline (O2O) loyalty program includes Dunkin' Donuts, Quiznos, Red Robin and Taco Bell. Plink members can now earn Facebook Credits at more than 25,000 locations nationwide.
