Hasn't happened to me much but once I bought a bass from a TB member and the guy charged me $20 for packing materials. I receive the bass in a old bare bones guitar box he probably already had or grabbed from a store, with 2 or 3 random pieces of styrofoam. No neck or body protection at all so the bass was 'floating' around the box during shipping. Preamp knobs were bent and a straplock was banged and was loosefitting! I was pissed! And this is from a guy who owns several high end basses (this bass was a FrankenFender)! I seriously doubt he would have packed any one of his high end basses like that! Besides ettiquette, I think a sticky should be put up with instructions on how to ship basses and amps and if not followed, maybe give demerits or temporary bannings!
Was the bass in a gig bag at least? IMO that should be part of packing. It HAS to be sent in a bag at least. Even if it's a cheapie. I know that places like MF ship out guitars without cases all the time but I don't agree with that either.
