7-Eleven is offering customers a free way to beat the heat on Wednesday.

Participating stores will give away free slurpees from 11 a.m. to 7 p.m. The company is calling Wednesday "SlurpFREE Day."

Customers may only get one free slurpee. The company recommends calling the nearest store before driving there because not all stores are participating and the event will go on until supplies last.

7-Eleven has set up a Facebook page with more information on the promotion.
