Thursday, May 19 is the first day the pizza is officially available to order, but Taco Bell Rewards members have early access Tuesday and Wednesday when ordering on the mobile app for in-store or drive-thru orders. Loyalty members who joined by the Super Bowl also will have a reward to get the pizza for free, redeemable through June 1. As an IOU, Taco Bell Rewards Members who received a mystery reward back during the Big Game will score a free Mexican Pizza when it’s back May 19, and loyalty members will get first dibs with early access to the menu item beginning May 17. The free pizza reward is valid from 5/19 through 6/1 and redeemable only via the Taco Bell mobile app for in-store/drive-thru pickup orders.
