u/Whisky-354

I bought a vintage seiko from Mercari using Buyer yesterday, nothing afaik has shipped or anything but buyee have told me they've bought the watch.

I was looking on eBay after the fact and noticed there were about half a dozen listings of the same watch, same photos and everything but almost double the price (the seller appears on Mercari to be a private individual, not any sort of commercial op).

So I'm wondering whether there's a bit of Japanese drop shipping going on here, or if I've stumbled into some sort of scam?
