Anyone have experience with yub.com? I just came across it, it's a combo cash back/hot deals/reviews/meet people(?) site. It has some referral thingy I think, but I'm not trolling for that, just curious as to the perceived value of this over some of the numerous other cash back sites. The percent back values seems as good or better than the others. Oh yeah, the name is "buy" backwards - cute, eh?
