Most Halloween spending is thrown out by November. Here is the part that is not.

Americans spend more on Halloween decor every year than on Halloween candy, and a large share of it goes in the bin on November 1st. Inflatables tear, foam props crack in the attic heat, and the one-year-only novelty piece stops being funny the second time you see it.
The decor that survives is the decor that is really just lighting. It stores flat, it works for more than one holiday, and it does far more to a house at night than any amount of plastic in the yard.
The Deal NestA projector covers an entire wall or garage door for the price of one mid-size prop, and it is the piece that actually reads from the street. This is also the category that sells out first every October, which is the argument for buying it in the first week of the month rather than the last.
The Deal NestThirty-three feet, under fifteen dollars, and connectable, so the run scales to the porch you have. Purple and orange is the one color combination that says Halloween without a single Halloween-shaped object involved.
The Deal NestA doormat is the smallest possible commitment to a holiday and the one guests see up close. It also solves the perennial October gift problem for the neighbor or teacher who already owns everything.
The Deal NestFlameless pillars carry Halloween in October and then move straight to the Thanksgiving table and the mantel in December. Anything that works for three holidays has already paid for its shelf space.
The test before anything goes in the cart: will this still be usable in three Octobers, and does it fold flat? If the answer to both is no, it is a costume, not decor, and it should be priced accordingly.
