With temperatures still in the toasty range, this may be one of the most economical ways to stay cool. Wendy's restaurants are selling small Frosties for 50 cents.

We're not sure exactly how long the promotion lasts. Maybe you'll remember the restaurant chain offered the 50 cent Frosty promotion back in May as a celebration of summer. Now it seems the discount may be marking the end of summer. Boo.

Grab your 50 cent chocolate or vanilla Frosty (maybe buy 2) while you can. Pick up some fries too. It's a tasty treat when you dip the fries in the Frosty; just sayin.'
