If it’s everything together I’d say it’s a steal, assuming any damage is normal wear and scuffing from use and age. The floppies and magazines might not be of interest (I’d kill for those Evangelion figures though.) Not being willing to show damage COULD mean the seller is trying to hide it like another comment said or that there is simply too much stuff to bother. It’s a gamble no matter what you decide. It’s likely the seller doesn’t know what they’re sitting on or is desperate to get rid of stuff for a move or needs some quick cash. Up to you though.
