The thing I don't get is why stores would have seasonal shit that they'd discount sharply to get it out. Fucking put it in storage and try to sell it next year (and maybe if after 2-3 years it doesn't sell, hopefully with maybe some thought on adjusting price, then clearance it).
Oh, I give zero fucks about "oh my gawd, they start X-mas early every year" (which most of the people bitching about that are the ones claiming there's a "war on X-mas" but then they tend to be hypocritical idiots in general). Have it year round for all I care. Maybe design things so they could be used for more than just one specific holiday/event. Especially if its stuff like LED light strings. Or those light projectors, make them programmable to show different scenes/designs/colors. And doubly so if you are smart about it (like put in a permanent lighting setup when you build the house so you don't need to put it up and/or take it down every year, and if you are thinking about it from the get go you could make it suitable for other times or even everyday).
