I had a $10.00 off GrubHub coupon for a local restaurant. I went to GrubHub, Placed My Order, entered the coupon promotional code and my credit card info. When the receipt came up it had not applied the coupon. At this point I could not cancel my order. I called GrubHub and I was told by a representative that even though my coupon had not expired it could not be honored because the restaurant had already redeemed its quota of coupons and my coupon would not be honored. I asked to speak to a supervisor and my call was disconnected.
If there are only a certain number of coupons that will be honored, then restaurants should only receive that amount. This restaurant is still handing out these coupons.
