I bought a phone on eBay last month. The seller insured it with USPS. When the phone arrived with a cracked screen (the listing had photos of a not-cracked screen) I photographed the damage and submitted a return request with eBay. The seller then filed an insurance claim with USPS.

USPS sent me a letter, requiring me to present the damaged package (and its contents) to my local postmaster. I documented this to the seller via eBay, but complied with the government authority -- I didn't want the seller to lose his insurance claim because I didn't comply. The postmaster kept the package, saying it was a requirement.

Once the phone was out of my hands, the seller denied the return, keeping my money, while presumably keeping the money from the USPS insurance claim.

I have no recourse with eBay.

For anything higher value, I have hobbyist forums I have 20 year memberships on where I can spend the time to due diligence individual buyers and transactions thoroughly. Even here I often don't get maximum dollars as I may have 3 offers and go with the person I am most comfortable transacting with.

And even on the higher end, it's easier to just do a trade in at a retailer instead of trying to extract maximum value doing business online.

On the lower end the problem is it's not worth the time to do the due diligence, and there are a tremendous number of time wasting tire kickers for lower value items. So I end up giving stuff away or just holding on to it, which is a shame.

I was looking for a phone. Lots of sellers will list things as brand new which should imply new in box (unopened packaging). After you carefully read the listing, they actually mean open box which is far more variable.

Ebay does not care at all. It makes the search basically useless.

The thing that makes it less likely is that the buyer and seller had multiple transactions together which is uncommon for eBay. And also if the stuff you got was expensive. Maybe buyer really just put the wrong address and neither side can do much to get the item back once delivered?

Just a recent example I had.

I was looking for a new camera. Finally settled in on a Fuji X-T3. The prices on legit camera places like B&H, Andorama and MPB were running around $800 for an excellent condition body. It went down from there in price. Found a body on ebay for $790. Right price, albeit a bit less and for a silver body. There has been an increase in demand for the silver body since Fuji announced they will no longer make them. Most silver bodies have been pushed up over $800 for even a decent condition body.

After kind of going back and forth over whether I wanted to make the purchase, the seller messaged me with an offer of $750. I was leaning on purchasing, but just as an experiment, I sent Claude the link to the auction and asked if it saw any red flags.

Claude pointed out it was a fairly new account within the last few months. Yes, it had 100% seller rating, but they only had six sales with zero user feedback. They also were not accepting returns. For a $700+ purchase, this was too many red flags and I ended up getting something off of MPB instead.

I believe this is the scam. Set up two accounts. Sell one account to another account with a fake user and address. In this case, your address. Ship useless stuff to fake account, boost your rating in order to ease people's anxiety over ordering from someone with less than 100% seller rating. If the person getting the useless junk emails you, say you'll send a return label, then never do it.
