Seems to be an error on the Uber Eats Page for Domino's, giving away 3 free pizzas as part of their 'THREE10ER Deal'. Price is for delivery so a pretty decent deal. All you need to pay is the delivery fee, which becomes $1 with cashback (Shopback) or free if you spend over $30
After 3 hours and 621 comments the error seems to be fixed in most areas. Hope you all enjoyed the cheap pizza!
