Figure the cash discount, if any. Check that you are charged the right amount. If using a credit card, check your receipt to be sure the amount billed is the amount on the pump. Take your card and any carbon paper from the credit slip. If you have a problem or question that is not resolved with the gas station, contact your weights and measures office for advice.
Some people heat their homes with firewood.
A cord is 128 cubic feet of firewood. To be sure you have a cord, you can stack and measure the wood. You can stack the wood in other ways, too. Get a receipt which shows the seller's name, address, and phone number, and the price, amount, and kind of wood purchased. Write down the license number of the delivery vehicle.
