I used envelopes from junk mail and bills I pay online to mail several hospital bills.
The comforter on my bed is reversible so I flipped it over to give the room a fresh look.
Cleaned my kitchen floor with vinegar.
Added vinegar to the rinse cycle while washing a load of dish cloths and towels to freshen them up.
Made a menu and shopping list for groceries for the week. Total was $110. After using my reward card ans a $5 off/$50 coupon, I paid $68.
Decluttered my pantry and kitchen.
Had to buy a new battery for the riding mower and was charged a $7 core charge. I took the old battery back and was refunded $7.63.
