Let me elaborate.
I'm fully aware of the different country extensions. I most of the time use .com. And it's one of my problems. It's retarded that the extension all work like shit. I'm swapping between: .com .de and .co.uk.
Currencies are swapped. Shown in dollars, while filtering is in local currency

I get import cost that are simply ridiculous : 4 USD part, shipping 26 USD (for < 50 grams) + import 12 (while this way below the import threshold)

The possibly to do the import yourself is not possible.
Then there are a ton of sellers where it says "contact seller for shipping cost", and they simply don't reply.

( ok, may not eBay's fault. But I suspect it's hard to setup the "specs" for sellers, which leads to this bs)
I "check" follow this search, and tada (!) ton emails, but when I click the item I often get "doesn't ship to your country". When I asked eBay about this, they claim everything works fine. Right.

On top the whole interface is so outdated. A 10 year old designs a better UI. Im using eBay for well over a decade, and its basically still the same.
It's just feels messy. Maybe that's the charm?
The ONE good thing is buyersprotection. But that's about it.
