What are your kiddos wearing for Halloween? I usually prefer homemade costumes, but I'm very, very tempted to buy DS a costume from Zulily. He wants to be a ghostbuster (DD is going to be slimer) and we don't have anything he can wear that even remotely resembles a ghostbuster.
They have neat adult costumes, too! Some of them match the kid costumes--so you could have Daddy and Son both be Superman. Or Daddy as Batman and kiddo as Robin.
It's more than I would usually spend, but the prices on Zulily seem great compared to other places I've seen similar costumes.
