The economics of dollar stores
I absolutely love dollar stores.  I recently needed to buy a set of crayons for my son and the options were $5 on Amazon, $4 at Target or $1 at the local Dollar Tree (and the pack had 36 crayons, vs 24 from the other sources!).They're not the right place for everything, but for kids' art supplies, cleaning products, party paraphernalia, seasonal decor, etc, they can't be beat. They seem to have a pretty strong stigma for some reason (seems like most professionals wouldn't be caught dead in one) but they shouldn't. Great place to shop!
