I love to shop at thrift stores and yard sales. A few summers ago I found blowup costumes that were adorable. They were still in the box and I payed a buck and a half for each. I tossed em in the closet and four months later for Halloween I remembered I had them. I told the kids I had a surprise for them and the weekend before Halloween I pulled them out. They were so excited they wore them for play costumes even after trick or treating was over.
