Heard about Mrrebates.com on the MusiciansFriend coupon stacking thread. In addition to the 4-6% cash back you get from purchases at Music123, musiciansfriend, guitarcenter, zzounds, etc; you get 20% of any cash back that your referrals earn! I haven't seen anything like this chain done on TB, but I saw this on another site and it seemed like a great idea. So the chain is basically this: One person starts by posting a referral link. The next person joins mrrebates using that link, then posts their own referral link for the next person (everybody gets one referral this way). To get the link, once you have logged in, go to "refer a friend" and click "links/banners". I'll start: http://www.mrrebates.com?refid=654555 Sorry if this violates any rules or anything!
