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 me dollars store are the reliable place to buy toxic stuff, cleaning supplies and in general non-food item.
I like that it’s small and to the point.
The food there make me sad, though. It’s almost exclusively crap.
