Idk about being specifically a scam, but It is definitely on the seller because He shipped you the wrong thing for certain... scammers usually "sell" a bunch of stuff, blame Shipping for the lack of delivery that was never actually sent and then fold up as soon as they are called out.
Smells more like a braying jackaṣs that doesn't want to admit he shipped the wrong thing to the wrong place.
Check the sellers about page, those that don't have a specific location (eg Tennessee, Bristol) in favor of "USA", are most likely Chinese drop shippers not even stateside sending a local grunt to go get and ship whatever from where ever
I learned, from his local post office, this guy ships 70 or so items at a time. He uses some manifest list thing when shipping out. The post office only scans the list, then sends items to next spot without physically scanning each package.
I see lots of complaints about USPS near Atlanta and about these manifest lists. The Shiiping label said 4 lbs.
An example…
“I recently started using the bulk shipping manifest / bulk shipping form per my local post office request. I can print the labels, print the scan form, and get the form scanned at the post office - no problem. The problem is that several packages included in the "one bar code" manifest sheet do not show up as being in the possession of USPS. If I go to the individual tracking for a particular package, it shows "USPS awaits item", even 3-4 days later after USPS has had it for those 3-4 days. So I went to my local post office and ask why. Of course I was told it was a "bug". The nice lady ask for my receipt for the 5/3/2022 scan form. I gave it to her. Then she was unable to find the acceptance bar code number in the USPS tracking system for the number showing on my receipt. Wow - imagine that. She said to not worry, the packages "should get there". So now ebay sees the packages incorrectly as not being shipped and they still show up in my "awaiting shipment" even though USPS has had them for several days. Now the false late shipments are showing up in my seller evaluation. Anyone else having trouble with the bulk shipping feature, which is supposed to improve the "seller experience"? So far, my experience ain't so good. Thanks”
And then the eBay seller feedback.. 300k transactions. 98.8% positive.
Was told correct item was shipped now. I asked what method of shipping and new tracking #…
His response, in all caps….
