Just for reference:
I bought a bass last month for $600 on Reverb. Seller paid UPS themselves to pack it, but it still showed up with a gnarly gash/chip on the bottom-rear area of the body. By Reverb policy, the seller pursued a damage claim with my photos of the box and bass. He got paid out $600 for the claim but wan't refunded for his cost of shipping. It was his right at that point to send a call tag, pay UPS local to me to box it up and ship it back to him; but we agreed on a $500 refund and I kept the bass.
