If you're looking for a way to beat the heat as sweltering temperatures continue to punish much of the nation, you can stop by any 7-Eleven today for a free Slurpee. National Slurpee Day is held every year on the 11th of July and there's no purchase necessary. For the 97th anniversary of 7-Eleven, the store is going all out. You can pick up your freebie at Speedway or Stripes stores too. 7Rewards and Speedy Rewards members can also get a coupon for another free small Slurpee between July 12-31. The free small Slurpees come in a special edition cup designed with the Children's Miracle Network Hospitals. Customers can also support the charity by making a donation when they come into stores.
