I ordered too. Brand new account and ordered from their website. Applied the code. No indication it was applied anywhere other than getting the quick green checkmark in their promo code box.
Talked to two CSR's from GrubHub. One told me my code wasn't applied and to try on another order. The other told me my code *was* applied but I won't be able to tell.




So....... was it or wasn't it?

There's some people saying GrubHub has told them the pizza codes themselves (not the free delivery) are all gone and no longer available. Either GrubHub doesn't know what's going on at all or Square is offering a finite amount of digital codes that sold out hours after the promo started.
