I doubt it. Zero profit (since I charged the going rate) and a real waste of time/gas to drive to my house to pick up a single pair.
The fake sellers must buy them by the crate for cheap to see any real profits.
If you charged the going rate for pre-used, maybe the buyer is planning to put them in official looking packaging (likely really official packaging picked up elsewhere, perhaps from their own purchase of an official product) and sell them as new for a profit?
Probably more likely:
1. Buy a new pair off Amazon.
2. Return the fake and get a refund from Amazon.
That does seem a more reliable option. I need to update my thinking of I want to be a good scammer!
