I don't mind them springing up sometime in November; I realize the flurry of shopping that starts on Black Friday (or Black Thanksgiving, or Black day before Thanksgiving as it is now becoming) kind of leaves stores in too much of a crunch to worry about decorating.
But dang, let me enjoy my autumn while at lasts. At least don't have Christmas trees and wreathes in the seasonal section when I'm still trying to shop for my Halloween party.
Craft stores are different... because you need to get stuff early if you're going to make it in time for a holiday. So I'm okay with Halloween & Christmas stuff popping up in craft shops in August. But for other retail stores... give me some time. I don't want to think about the holiday season in mid-October.
