This may be a silly question, but I have never bought costumes after Halloween. My mom has this idea that she would like to get my boys (DS 3 and 4) costumes for christmas as a big dress up chest. They make it easy for girls, but my boys have worn out all thier halloween costumes playing dress up (ok DH will kill me for that wording .. they are "pretending") after halloween. We had a collection of Woddy and Buzz, Mickey and Simba .. adding Captain Hook and Peter Pan this year. I was just wondering if they go on sale online or if you have to go to a store or if they even go on sale so she can put together a really nice costume chest for them.
