Paying system is through Facebook (weird , huh?). The way it works is by logging in to Facebook through a personal app and notify the person who the deed is intended to. This way 'buyers' are forced to complete their promises, and most of them leave pictures of the store on Facebook as proof that a good deed has been completed.
