nobody does this. Keeps halloween candy between years?
why? there's no advantage to having a "big stash". halloween candy decomposes into empty wrappers naturally anyways. It has a half life of 9 days.
After Halloween specials on candy are amazing. Theoretically, people could just always buy those deals and save them for the next year. That holds for all after season items.
This is a perfect strategy for buying clothes, but candies? nobody stores candies this long :)
If you were buying winter tires sure but Halloween candy is on sale every year and the cost for most homes is negligible so it's unlikely people are stockpiling it
There’s no advantage to a big stash, but it’s easy to overestimate the number of trick-or-treaters, have a ton of candy left on your hands, and just stick it in the closet for next year.
