Wow, that is insane. I literally just went straight to WallyWorld and bought the original set (it's somehow still on clearance there for $200) just so that I can build this MOC instead!! Thanks for posting!!!
The LA address is most likely a forwarder. It will get delivered there and you'll be home free. They can forward it to Bulgaria and it doesn't matter what happens once it arrives there. If they try and say that something was broken or not as described, they would have to send it back. They won't. This has always been my experience.
Hmmm .... should I be worried? This is the buyer's address on a BL order:

Account was created in early May. 4 Feedback. Ordered close to a 100 pieces of one part. Picked my most expensive shipping option. Curious.
