This Old Navy by far exceeded my expectations. They had everything laid out and it was a pretty neat store considering a hard-core sale was on. I had a groupon which I wanted to use, so I found a couple things and then headed to check out. I showed the salelady my groupon, and she tried entering it in, and it wouldn't go through. She tried 4 or 5 times with no success. Then she voided the sale and tried it ALL again. And it worked. I forgot her name, but she was super nice at making sure she could use my groupon. Thanks Old Navy!
