pdh:
I mostly use cash & pickup for TradeMe - buying & selling - removes a lot of issues about the state of the goods at points of offer / shipment / delivery.
Occasionally I have trusted a suitably reputably vendor - to ship me a 200-500 $ item across the country - that's probably my limit.
As a vendor, either on TradeMe or on your proposed system, I would be concerned about the scam purchaser...
'Nah - it never showed up / arrived defective.' is an easier scam if no money has changed hands yet - or is in escrow.
Building some smart guardrails to stop that sort of purchaser dishonesty would be a strong point of difference.
We're adding a pickup flow: exchange location suggestions, in-app meeting coordination so the agreed price and item are on record and verified identity on both sides before the meetup. Making local deals safer than Facebook is a separate job from making shipped deals trustworthy and we need to do both.
scam purchaser point: you're the third person to raise this and I'm taking it seriously. The escrow model as most platforms implement it is effectively a buyer's weapon. We're building the seller-side version: buyer dispute history visible before you accept a transaction, mandatory timestamped evidence for any damage claim and new accounts can't immediately run the scam on a high-value item, and mutual ratings that actually carry weight. The pitch to sellers is going to be that we protect them as hard as we protect buyers.
