Bing (clubbing.com) was and still is a gimmick site. You sign in with your msn / hotmail account and play all types of games for points / tickets. Of course MS uses Bing as search engine. Some games are actually a nice challenge and by amassing enough tickets, some decent prizes can be had. But now, some of the better ones are in ClubVIP which requires you to use IE and the Bing Toolbar / Search Engine. That said, I still have 28,000 tickets to use (if I see something worth getting)
So far I was able to get:
MS Office 2007 Ultmate
MS Vista Ultimate
Sony HandyCam DCR-DVD650
Magellan Road Mate 1340
Magellan Road Mate 1470
All for playing games and all Free
Have not yet used cash back, as most times it is for
stuff I do not need or at stores I do not shop at often.
