Spinoff to Bah Humbug - Where to buy pumpkins in midtown?

I've decided I'm buying a pumpkin tonight :) Does anyone know places in midtown where I could buy one? Nothing huge, just a cute little medium sized one. I'm looking anywhere around 55th & Broadway. I know there was a place on 8th & 53rd that sold Christmas trees during the winter, but I don't know if they have fall things too. Thanks so much everyone for helping me in my quest to get my DH in on the Halloween spirit!
