Chipotle has a deal on burritos this Halloween, but there's a catch

• Chipotle is selling $4 burritos for costumed customers on Halloween.
• On Wednesday, from 3 p.m. to closing, stores will be offering discounted burritos - or "booritos" - if you show up in a costume. 
• The $4 boorito is an increase of $1 from last year, as Chipotle has quietly raised prices on the Halloween deal over the years. 

Chipotle is selling discounted Halloween burritos - or "booritos" - yet again this year. But, in 2018, the burritos are $1 pricier than they were in 2017. 

From 3 p.m. until closing time on Wednesday, people wearing costumes can get burritos for $4 at Chipotle. Costumed customers can order in-store or via mobile app using the code BOORITO. And, for once, adding guacamole does not cost extra. 

$4 is a pretty good deal for a Chipotle burrito. However, for some people haunted by Chipotle Halloween festivities past, a $4 deal just doesn't cut it.

Last year, Chipotle offered $3 burritos to costumed customers on Halloween - making the $4 deal a $1 markup. 

When Chipotle initially launched its Halloween promotion, the booritos were free. That changed in 2010, when the chain started charging $1 for costumed customers who bought a Halloween burrito. 

Boorito costs have quietly increased on Halloweens since. 

Despite the boorito inflation, many people are still simply happy to get a discount at Chipotle.
