Beware buying vouchers from Teambuy and Dealfinder, they do not give refunds or credits for purchases that were made over 240 days ago when merchants don't honor the valid vouchers.
I have 3 vouchers with no expiration date, got rejected the first time, said not usable in the weekend, contact teambuy/dealfinder to get the refund, they said keep trying! Tried few more times, merchant said the don't accept vouchers from teambuy/dealfinder! Tried to get refund/credit from teambuy/dealfinder, got ZERO since over 240 days old!
Their policy doesn't protest their buyers, they shouldn't sell these kind of vouchers which have expiration day after 240 days of purchases, teambuy/dealfinder and merchants keep the money by not honoring the vouchers. Only winners is teambuy/dealfinder and the merchants.
