When selling your item in person, you’ll get paid in person. Before you meet with the buyer, discuss your desired payment method so you both know what to expect. When you meet, the buyer will get a chance to inspect your item. If they agree to buy it, they need to pay you on the spot before leaving with your item.
The safest payment method is cash. App-based payments like PayPal, Zelle, or Venmo are convenient, but they do carry some risk. Never accept checks, gift cards, wire transfers, or cryptocurrency; these put you the most at risk of fraud. Whatever payment method you choose, make sure that you receive the money before you hand over your item for good.
