Texas’ 2010 Tax-Free Weekend is scheduled for Aug. 20-22 … and if you think ahead, you could score some free food on one of those days. Just visit any Texas Chipotle on Aug. 17 or 18 and buy a burrito, bowl, tacos or salad. Then save your receipt and bring it back to any Chipotle in Texas to get another burrito, bowl, salad or order of tacos for free. While you’re saving some dough on back to school stuff, you can get a free lunch too.
