Re:Ask HN: Has anyone on HN ever successfully arbitraged eBay? by peter_d_sherman on Sunday January 27, 2019 @12:47PM (#19012774)
...That is, has anyone here on HN ever bought an item on eBay, and sold the same item on eBay for a profit?

If so, that leads to such sub-questions as:

How did you know/learn that you could make a profit on that item?

What kind of profit did you make?

How long did you have to wait to sell the item, that is, what was the turn-around time, etc.

(Inquiring minds want to know! :-))

Done it a few times after 'organically' researching some fairly high-value item that I actually wanted.

After I've secured one for myself to keep, there's a short-ish period of time during which I feel like an expert on the market for that item, and my "Saved Search" with email notification remains enabled. Sometimes obviously underpriced listings(s) then show up. Not much more to it than that.

I have, but that was mainly by pursuing low-visibility auctions.

Hardly anybody uses auction format anymore for anything but rarities/collectibles.
