Shipping goons
There are some real ones out there...
In fairness to UPS and FedEx, my side porch was a UPS receiving dock for 2 years of 2x/week Snap-on deliveries. In that time, I can probably remember 10 or so damage incidents or torn box/missing a few widgets. It was pretty rare, but stuff happens.
A couple years ago, I unloaded a lot of extra Jeep parts (normally odd-shaped, heavy, sharp, or a combo of) including a full 8 pt weld-in roll bar kit and sent it all UPS. I only had one issue (me forgetting a widget in the box-cost all my profit to send it separate & asap) I tend towards overkill with bubble-wrap or popcorn, suitable cardboard, and lots of good tape. Kinda jacks the shipping cost a little, but so it goes.
I've also bought/received a lot of Jeep & bike parts from far-flung vendors and private sellers via internet or phone and have had pretty much 100% satisfaction. There have been some tight schedules involved (normally due to mis-communication) but overall OK.
That's not to say that problems won't occur. As stated above, figure on a 'value' of the lost bar, and submit a claim to the shipper, and deal with the buyer as best you know how. Set the claim high enough to sport the dude a new bar then wait for the settlement??? What was it anyway?
