Is this marketplace seller who wants to move off-platform a scam?
Treat it as high-risk. When a seller (or buyer) pushes you off the marketplace to WhatsApp and asks for a bank transfer, gift card, or a “deposit to hold the item”, you lose every buyer protection. That's the point.

EXHIBIT · PASTED MESSAGE
Received via: WhatsAppEN
Hi, the item is still available! I have other buyers, so send a 20% deposit by bank transfer to hold it and I'll ship today. Let's continue on WhatsApp.
How to verify it yourself
Keep the whole deal inside the platform — chat, payment, everything.
Never pay a deposit by bank transfer or gift card to a stranger.
“Other buyers, act now” urgency is a pressure tactic.
Reverse-image-search the listing photos — scam listings reuse stock images.
