For reasons unclear, Sonic will be serving slushes for 79 cents all day today. No, it's not National Less-Than-a-Buck Slush Day or Frozen Fruit Day or another weird food holiday. But don't get us wrong, we're definitely not complaining about a good deal. 

Pop in to "America's drive-in" restaurant for a few of the dirt-cheap drinks: You can order up to four medium 20-ounce slushes (normally $2 each), so why go for just one? Opt for at least two and then swirl them together into a super slush using our pairing guide: 

ORANGE + COCONUT

It'll taste like you're on island time, but for less than two bucks. 

GREEN APPLE + GRAPE

Double the Nerds, double the fun. Plus, the tart green apple will help cut some of the super sweet grape flavor. 

CRANBERRY + LEMON

Strawberry lemonade? That's so last summer. Sweet-tart cranberry is where it's at. 

CHERRY + LIME

Frozen, fresh limeade with a sweet twist. Or a frozen cherry lime rickey. Either way, it makes for a striking swirled slush.
