Well, it was a good idea, but the costume area after Halloween is a huge MESS! Parts of costumes are tossed here and there. If you find something you like, you have to search at the bottom of the display for the matching mask/hat/whatever. Not easy! There were some Star Wars costumes that I wanted to get, but couldn't find all of the pieces. Same with Transformers.
But in the end, I walked away with 2 Human Torch costumes, 1 Mr. Incredible costume, 1 Spiderman costume, 1 policeman costume (with muscles!), and 3 NASCAR costumes for about $35. I also got myself a costume for $5 in case I ever need to be Pontius Pilate in Sunday School.
