There are still 15 hours left on the deal, and already nearly 820,000 have been sold. It's unclear how much of the revenue Living Social gets to keep. Despite the fact that the fine print says clearly that Amazon.com is "not a sponsor of this promotion," there has to be some help from Amazon.com to Living Social in this deal.
Amazon.com invested $175 million in Living Social in early December.
Note that the fine print also says that deal bucks can't be used for this deal, and also only one per person. However, some reported buying multiple gift cards, and also using their deal bucks, too, so it appears that Living Social modified the fine print.
Some are trying to game the system by using multiple email addresses and multiple credit cards. Those who do that could actually game the system twice if they "refer" the new email address. Meanwhile, if you're not on Living Social, take a stab at it and sign up. This is going to be a huge day for Living Social.
