It wasn't the mafia behind it, it was one guy (that wasn't part of the mafia) that got other people to help, one of those people being related to the mafia.
In 2005 the Monopoly game included Best Buy bucks, you were guaranteed at least $1 per sticker pull that could be used at BB. I sent in several hundred self addressed stamped envelopes and received one of the BB stickers and four of the monopoly game pieces per envelope. Ended up with several hundred dollars to use at BB and a shitload of free food for McDs. Didn't get any big prize though. The BB bucks had the ability to be used online, but it didn't invalidate it for being used in store. I ended up buying a bunch of the 360 launch games with the BB bucks online then going in store to use them to buy other things. It was great!
