Why no Halloween store at the Gallery?

Here's a question: with Halloween creeping upon us, knowing that South Philadelphia's Masquerade will soon be facing it's at-capacity one-in-one-out clientele, why hasn't the Gallery at Market East recruited a seasonal costume shop?

Sure, some of Burlington Coat Factory's sale items might qualify as costumes. But in a mall, a Halloween store brings seasonal foot traffic. At the Gallery, it brings in Philadelphians who thought the mall was closed and might think, "hey, I didn't know Aldo had a brand called Call It Spring, I'll have to come back here."

Of course this isn't solely up to PREIT, but those managing Market East's White Elephant missed a golden opportunity here. Even King of Prussia fields seasonal costume stores to fill its vacant shops.
