I put grapes, apples, oranges, etc. From other bags into mine at the grocery store. Use the same coffee filter 2-4 days in a row. Coast and drive under speed limit as much as possible. Re-use semi clean dishes so I pay less for soap. Wash my hair once a week ( use bar soap everyday ). Take the toilet paper from the bathrooms at school. I'm sure there's other things I do that I've accepted as normal that others view as cheap.
