I agree on drug expiration dates. Also some meds you can store in the freezer to extend their potency.

Yesterday I got some practical items - among other things weatherstripping that will save me come heating season and a mop. Dollar Tree was out of stock and Family Dollar wanted $6 to $10. I settled for $5 at Dollar General. This is why when I see mops at Dollar Tree I stock up. Eventually the style I like gets too worn and grubby to clean effectively.
