The cheapest Halloween “treat” I’ve given out were stickers. I saw $1 sparkly Halloween stickers at 90% off. Since the chocolate candy I like to give out often costs around $0.10/piece, I knew this was a good deal and bought them out. Each sheet got cut into 6 squares for a price of $0.017/piece.
When you see non expireable, portionable items on sale after Halloween, buy! and don’t forget to put it with your Halloween stuff so you don’t forget it next year.
Added bonus: highschoolers don’t like it, but the kids that you actually want to spoil do! Win-win!
