Some kids can’t wait to get back to school, some kids dread it. Either way, Sonic Drive-In wants to make all kids happy with kids’ favorite at a discount. On Thursday, August 14, the fast-food joint is offering 50% off cheeseburgers. The burgers are prepared with 100% pure beef, melty cheese and fresh ingredients — all made to order. (If you don’t like cheese, just order a cheeseburger without the cheese and still salivate over the savings.) There’s no limit, so everyone in “your homeroom” can chomp on a cheeseburger. If you wait until after 8 p.m., you can also take advantage of Sonic’s nightly half-price shakes promo. The deal is valid at participating restaurants. For locations, click here.
