Temperatures are going to be hot this Memorial Day weekend. It's a perfect occasion for a Burger King special: all 12 ounce smoothies and frappes are only a $1 each. No coupon needed!

Burger King says the smoothies use real fruit, so there's a health bonus (OK, maybe not that great of a bonus, but hey, it's a holiday!)

Smoothie flavors include strawberry banana and tropical mango; frappes come in mocha and caramel.

This special runs through Monday, Memorial Day. Not all BKs offer the special, so their website says.
