Chipotle Boorito

Chipotle Rewards members who visit a restaurant in costume from 3 p.m. to close on Oct. 31 and scan their Rewards member card at checkout will receive a $6 entrée offer.

This year for the 25th anniversary of the promo, Chipotle will bring back its Boorito Costume Contest that will give fans a chance to score a VIP Card, worth over $500 in free Chipotle.

Plus, rewards members can try the new "Chip-or-Treat" perk for offers like free guac, chips and extra Rewards points, once a week now through Oct. 30. After members purchase an entree, they will receive a "Chip-or-Treat" email within a few hours that contains a treat tailored to their preferences, valid for five days.
