Growing up, we had Woolworth's and Ben Franklin's. Woolworth's had a "soda fountain," which was just a small diner in the store with bar stools at the counter.
I shop at Dollar Tree for consumables, such as paper products like napkins, paper towels, and toilet paper. They have a spray cleaner called "Awesome" that cleans everything very well. The person who told me about it cleans houses for a living. It works and it's cheap.
I am leary of buying makeup and hygiene items there. It is cheap for a reason. Not all imports are good for you, so I also don't buy food items there. Anything that doesn't go in or on my body might be okay though.
