Groupon -

“Launched in November 2008, Groupon features a daily deal on the best stuff to do, see, eat, and buy in a variety of cities across the U.S., Canada, Europe and soon beyond (read: Space).”  Their philosophy is to sell stuff that they would want to buy.  No junk!  No gotchas!  If Groupon features a deal, they want you to feel comfortable buying it!

“Get $10 in Groupon Bucks when someone you invite gets their first Groupon. There’s no limit on how much you can earn!”
