If you have a Sonic Drive-In restaurant nearby, you might want to check the menu or the specials. The ones in my area offer half price shakes after 8 p.m. all summer long. Now, of course, we don't get them often, but once in a while it's nice to have a cold treat. At half off, you can't beat the price. It really adds up when you have a car full of people who want ice cream. They offer 25 different flavors, all of which are available under this discount, so check it out.
