I purchase Halloween items at Old Navy; however, I purchase them after Halloween for the next Halloween. I love to pick up their Halloween themed t-shirts for the kids to use next year for 99 cents each!! Normally $10!! I also shop for black sweatpants because those are pretty much a staple for costumes to keep the kids warm here in Michigan when the trick or treat. I like the Halloween themed boxers for boys, too! Halloween themed socks are always a good thing to pick up, for cheap, too!
