Gamasutra - News - Report: Facebook Testing 'Pay Later' Option For Credits Purchases
Facebook has reportedly introduced a "Pay Later" option allowing users to spend Credits, its universal virtual currency system for social games and apps, that they don't have and pay for them later. When users who have never purchased Credits try to buy virtual goods in a Facebook game, the social network presents a pop-up asking them if they want to pay later and receive a bill for the game. The site then sends an email receipt and shows a negative Credits balance on their Games dashboard.
