I use ebay heavily and I don't see it anymore, except for things that look like typos or people who clearly just don't know how to use ebay. There's no advantage to doing so because sorting/filtering includes shipping.

Sorting isn't strict (or perhaps affected by paid placements?) so buyers still have to look at the prices to see which item is actually the cheapest.

I still see it. Idk what the seller is thinking but I’m guessing they aren’t too smart.
