I am fairly regularly astounded at how bad a lot of for sale posts are. Blurry (or no) pictures, no suggestion of where the seller is, no description, etc etc. The second hand market is really struggling just now, why people aren't making more effort I do not know.
If a seller can't be bothered to take photos that are in focus for a bass that they're asking £££ for then I'm not sure I trust them to be bothered to pack it properly either.
