I purchased a voucher from a group buying site for Pro Platinum Auto Wash -- this company has no intention to fulfill their agreement. When I called they were rude and said they had sold over 1500 coupons and that I would have to wait. About a week later I saw another offer for their company on another group buying site!
They are just collecting money and have no intention to fulfill their coupons. I contacted the second group buying site to warn them (they had already sold another 500 coupons). I got my money back from the first site where I bought my coupon and the second site removed the deal.
Warning -- get your money back -- this guy is just going site to site collecting money!
