GB concluded!I had two packages still laying around here that were returned to me (not picked up or wrong address). Gotta admit I forgot about them for a while. Due to corona I had some more time and finally took care about those two. They were the reason I couldn't call this GB concluded.
Now I finally can
From those last 5%, some switched to SKB2 and some got a refund.
Overall I'm surprised that from roughly 200 packages, only three in total were returned to me. To my knowledge, all the rest arrived well. Some of you may remember how finicky I was regarding the addresses. With quite a few I wrote a few times back and forth just to make sure the address format was correct. Looks like that effort wasn't for nothing. Managing all your data via google sheets got quite messy in the end but it did work out.
Future service:
Anyone who owns an SKB (via GB or second hand) can always contact me in case he wants to get a custom plate, I'll make the DXF file (free of course).
Final note:
A lot didn't go as planned which lead to quite a few delays. The support from all of you guys was outstanding and a huge motivational factor that helped me push trough. I've learned a lot and this experience will help with future projects.
Huge thanks to all participants!
