They are prepping for Christmas at our store, or the Holidays, as I refer to it for customers. "We get more of (whatever weird item they want) around the Holidays." The timing for displaying seasonal merchandise is tricky; you want to do it soon enough that there is plenty of time to sell it at full price, but not so soon as to shock customers.
The funny thing is that usually customers usually ask for the seasonal items before we have them out. "When are you going to get your Thanksgiving stuff?" Then other customers complain that we are forcing the holidays on them too early.
One of my favorite times of year is when we have both Christmas and Halloween items on the floor at the same time. Why not have some glittery spiders or bats or pumpkins on your Christmas tree?
