Just don't ship UPS it is as simple as that.
I got burned on a claim for a $1500 scanner I sold on ebay that arrived broken. Even though I packed it with 3-4 in of peanuts tighly around it. The buyer went ******* becaus eit didn't work, I had insured it, but because he didn't keep the packaging it was denied.
He came back after me for it, but I was luckily able to get Paypal to take my side, as it was his fault for throwing away the packing materials.
Never again will I ship anything of value via UPS, fedex, is great for claims, broken glass, broken electronics, and lost packages they make you wait 2 weeks then boom they give you a check. I haven't ever had a complaint with Fedex.
