I just received my speakers today. I never got a confirmation email that they shipped so, i dont have a dang receipt for purchasing. Also, the rebate form says "Offer not valid with any other rebates, offers or promotions." So, WTF!?! If i get them to mail me a receipt it will have the $20 off coupon listed, so what are the chances of actually getting the $20 mail-in rebate?? I'm thinking about returning these suckers, i only ordered them cause they seemed like a good deal on a second set of speakers (i dont really need them). Any opinions??
