cups with sports team logos on them. Something you would find at the dollar store or buy in 3-packs and walmart for $2. They are selling them for $18. And if you sell one, you get to keep the demo cup they sent the kid home with. But if you don't, and you don't bring back the demo cup, you owe them $18.
Also they had an assembly the other day where they had some guy showing some cool yo-yo tricks. Then they came home with order forms to buy all sorts of crappy yo-yo crap for 3 times what the same stuff would cost in stores.
