I just had a look at your eBay store Ice-Tea. Clicking the link on my phone takes me to a site showing everything in Euros and I can see 36 items.
Copying a item number, searching that in the eBay app, seeing sellers other items, I can only see 14 items.
People have been confused that I’m happy to pay more for shipping than the item cost, but overall it was still better than other alternatives. Test equipment is really not that common down here, so we have to pay the premium. Of course, there are countries that have it a whole lot worse than us.
