Terrible customer service. Merchants should have a grace period. Emergencies arise where the coupon event cannot be redeemed. Groupon is very understanding about it and will give FULL refunds. The deals they have are far less superior than other merchants. And that is why I will continue my business with Groupon and NOT LivingSocial. I purchase at LEAST one/two coupons per week. Because they were not accommodating with my situation, a single $100 voucher cost them literally thousand of dollars of my future business. Good riddance!
