Hello Seiti,.
the message that was displayed, is probably not ebay, it's vendor, which excludes shipping in certain other countries.
For example, has rareniceplants the shipping were canceled after Germany, because too many items not on the recipients were or withheld by the customs. It has made so much problems to the provider has decided at some point that a shipment is no longer viable for him and the bidder after Germany.
Another is dylansbulbs, which unfortunately also not sent to D.
Sometimes it helps to write the provider and agree that he still (at risk of buying) sends to D.
A detour is that you can send to an address in a country that was not excluded. I ever did about an acquaintance in the United States, but that will be expensive to Porto and the travel time is natürlichauch longer.
Belgium as a recipient address should be interesting, because there supposedly quite lax customs controls should be.
That will be displayed on the phone any more than on the computer, I didn't even...
The trick with the search for specific providers (link in your post) works also not more fully; I often get the message that the allowed number of requests for the day was exceeded for some time...
Vice versa, there is also the problem. If offered by ebay Germany, offer in some other countries, for example in the UK is not displayed. I called once on ebay, how can that be, but who could not explain this too me, except that have conditions sometimes different other countries for certain products.
I started then to make offers on ebay.co.uk using the special option "show on ebay.com" that but more cost 5 or 10 pence; then, it appears the article in more countries.
However annoying and regrettable that there are to ebay no real alternative...
(UN) Happy bidding,
Bernhard.
