Insurance WILL NOT insure anything!
Rule #1- overpack it with the right packing material. If you're not sure, ask the manufacturer. DO NOT trust the guy at the UPS store. They don't know electronics.
Rule #2- NEVER EVER pay or arrange shipping for an item you're buying. This makes YOU the responsible party if damage occurs.
Rule #3- NEVER ever sign for a damaged package if it's through a freight company! Even if you write "damaged" on the BOL, you're still responsible for returning the item ON YOUR DIME IF returns are accepted. If you think it's insured, you may be right. Freight companies pay 19 cents per pound for freight claims! Third party insurance sounds like a nightmare to me.
Rule #4- hold your breath until you receive, or the buyer receives the item and leaves you positive feedback. Control is all with the buyer unless they surrender their rights by being ignorant or too lazy to learn the rules.
Rule #5- If an item is that important to you, drive there if possible!
I learned these things through experience. Hopefully you'll avoid some of the headaches I've endured. Joe
