Medication
You should avoid buying medicine at the dollar store if you could. They did not go the standard tests that pharmacies give out. They might even be mislabeled. It is better to go to a trusted store instead.
Spices
The dollar store won’t have all the spices that you want, but it should have parsley, pepper, cinnamon, and basic stuff. You can get these at a huge container for only a dollar! What a steal, right?
