So I decided to give you guys a final update, even though I at first I wasn't going to. I don't want to discourage anyone, but here it goes nothing.
I contacted A more than 8 weeks ago and ordered two bottles via private courier to germany. I used Bitcoin to pay. Communication went well, package was sent a few days later. It arrived within 8 days at the german airport and tracking did not update for almost a week after that. Then I got a letter from my local customs office, claiming that there are issues with the package and it needed to be picked up. I went to the customs office, opened the package right infront of the officer. They inspected the bottles and did not find anything suspicious, however they demanded a proof of value, which I obviously couldn't provide. So the first package was seized three weeks after I ordered.
I contacted A a second time asking if he can send another package. He gave me a significant discount and the package was sent a week later. It arrived within 7 days to germany, got through customs without any problems and was sceduled for delivery on a wednesday. So I took the day off, waited at home - nothing. Tracking says that it coudln't be delivered and is ready for pickup at a post office. To cut things short, the package was lost, most probably stolen. That was week 5 after the first contact.
So I wrote yet another email to A, ordered a third time. Third time's a charme, right? He sent the package with a delay of one and a half weeks. Got to germany no problem, however tracking says that it is stuck at a parcel center right now. Tracking did not update for more than a week. At this point I accept that the package was lost again. I contacted the local postal service, they said it can take a few month to find the package.
A offered me to send a 4th package for free. But I can't wait any longer. I wrote more than 40 emails to A, almost always got a response within 24 hours. In rare cases up to two days. A is legit and very helpful, however the logistics has been a nightmare for me. I will be going with my backup plan, the exitbag now.
If you have any questions, feel free to ask away.
