What are things that potentially fraudulent buyers do?

Ask you to wire money into their account.
Buyer offers high-value (but fake) cashier's check in exchange for the item for sale. The value of cashier's check often far exceeds your item and the buyer asks you to wire the balance via money transfer service. Banks will often cash these fake checks AND THEN HOLD YOU RESPONSIBLE WHEN THE CHECK FAILS TO CLEAR . Scam often involves a 3rd party (shipping agent, business associate owing buyer money). We would strongly discourage you from wiring money.

Recommend an unfamiliar escrow or payment service.

Place large orders to be sent to a foreign location.

Say they will pay you half of what's due before they receive the item, and half payment afterwards.

Will not provide you a verifiable telephone number.

Pay with an international credit card or cashier's check.
