Krispy Kreme, Chipotle and more offer Leap Day deals to celebrate the extra day

Leap Day, Feb. 29, only pops up on the Gregorian calendar once every four years, and retailers across the spectrum are making it count.

This year, Wendy's, Chipotle, Krispy Kreme and Staples are all offering consumers deals to cash in on the special occasion.

Krispy Kreme offers deals on its classic glazed treat

The popular doughnut chain will be offering its famous original glazed doughnut dozen for just $2.29 on Thursday, when purchased along with a full-priced dozen.

For customers looking to buy doughnuts for a Leap-Day office party or any group gathering, the second dozen would come out to just 19 cents per doughnut.

Krispy Kreme will also offer a free glazed doughnut to any customer born on Feb. 29.

"An extra day in the year is an irresistible opportunity for Krispy Kreme to be extra-sweet to our guests," Dave Skena, Krispy Kreme's global chief brand officer, said in a statement.

Chipotle customers can score free guacamole

Chipotle Rewards members can cash in on the extra day in February by using reward code "EXTRA24" for a free side of guacamole on Friday.

Leading up to Leap Day, the Mexican food chain is challenging customers to find key words hidden in its Instagram content and text the words to 888222. The announcement notes that ordinary text and data rates will apply.

For each word, the 366th texter will receive free guacamole for one year.

"Our guests understand that 'guac is extra' is not just a phrase, it's a testament to the quality and freshness of our real food," Stephanie Perdue, vice president of brand marketing, said in a statement. "There's no better way to celebrate an additional day on the calendar than with our iconic guacamole not being extra."
