In the email sent to users, GrubHub explains what will happen next for those who still have prizes or plays left:
1. If you’ve got prizes waiting to be redeemed, don’t worry – they’re still yours. They’ll expire on their normal date. Any available prizes will be appearing as you browse menus.
2.If you’ve got saved Yummy Rummy plays, they’re yours too, but only until December 29th. So hurry up and test your mettle on the rocky rapids of fortune.
And if you’re still upset, you can express your dismay in this GrubHub survey.
