You will also want to accept cash on pick up. So if the buyer pays via paypal, refund the buyer using the refund link in your paypal account. The reason for this is if a dodgy buyer pays with paypal, then picks up the fridge, - he may later file a claim for 'item not received'. Obviously you will not have a delivery confirmation number on a pick-up, so you would lose the claim, and the buyer gets the fridge and the money.
