Here's how it went down:

Note that they’ve sold so much that even 1k neutral ratings are barely registering - they have “100% positive feedback”
I bought a cheap tool from this seller on ebay. Tracking number was provided showing my town as the destination. About four days later, I get an unprompted ebay message from the seller: “I monitor all my shipments and sometimes there are problems so I’m proactively sending you a new one, here’s a new tracking number.”
The original tracking number showed a message I’d never seen before “Item seized - counterfeit postage”. The new tracking number showed postage that had been bought back in January, but never entered the mailstream. Huh. I suspect that buys them time while they re-ship.
I did eventually get the item after another tracking number was provided.
My suspicion is that the seller uses counterfit USPS postage on 'x' number of packages to juice their margins. If you look at the neutral reviews, you can see a pattern — slow postage, lost package, had to replace, blah blah. Look at the positives — rave reviews at how fast things are arriving. Probably because the seller is “paying” for higher end postage via scamming the USPS.
And only when they get caught by USPS do they need to re-ship an item. They must get away with it enough to make it worthwhile
