Now the next problem is finding a shipping company who will get what you are sending to the destination undamaged.
When I retired I had my LBS box up my old rust bucket, it was transported to it new home by me in a Penske truck. When I unpacked it was just like I dropped it off for packing.
I recently bought an Italian frame on line, the seller did a S**T job of packing the new frame, and fork. UPS did a crap job of handeling the box with care. Box arrived with part of the frame hanging out. It was bent and scratched. UPS believe it or not just left in by my front door.
Frame & fork was returned to seller, I am waiting for a credit card credit, or I will dispute the charge as I did not sign for item, can prove it was sent back, and las it arrived back as seller.
Best advice is pack what you send like a monster gorillas are going to be handeling it, as people in the shipping business don't care if it is a family heirloom, buck of dung, or bicycle frame. To them it is just another box, that gets treated liike a buck of dung.
