← Scam Defense: How to Keep Your Money
Lesson
Lesson 10. Marketplace listings: deposits, shipping, and “safe checkout”
Keep the deal inside the marketplace, and spot any attempt to move it to a private chat or an outside link.
The deal lives inside the app
Where scammers take the deal
A listing is a rare place to talk money with a stranger, so the marketplace protects you: chat, payment, and shipping live inside the app. A scammer first pulls you out — to a messaging app and “his” payment page. The rest is scenery.
A worked example. You're selling a bike. In the marketplace chat: “Hi! I've set up shipping, pay through safe checkout: hxxps://market-delivery-pay.com/order/88214.” The page asks for your card number, expiration date, the three-digit security code on the back (the CVV), and the code from the text. The sign that settles it: the payment has left the app. Inside the app, money reaches you without outside links.
Remember which way money flows. For money to reach your card, its number is enough. The expiration date, the CVV, and the code from the text are for taking money, not sending it. Asking for them “so I can pay you” sets up a transfer from you.
The scam's mirror half is the deposit: “Send a deposit, I'll take the listing down and hold it,” “another buyer is ready.” The marketplace can't see or refund money sent to a stranger outside it.
The lesson's rule: chat, payment, and shipping stay inside the app. “Let's move to a messaging app, it's easier there” isn't convenience — it strips the deal of its protection. Pull the emergency brake here: no arguing, no exposing — just bring the talk back into the app.
