I haven't seen all that much really but haven't been there long.
There's a small pile of dubious manga that is all in Japanese.
One letter opener that is basically a repro dagger. I mean it's a fair size and actually already has enough of an edge on it to be used as such

Bunch of R rated movies, which company policy doesn't allow us to sell...not much unusual there but I haven't gone through it for a while.
Brazilian butt lift guide, which maybe is ok to sell but it's just there anyway.
Out of region movies can't be sold either but there aren't any of those there atm 'cos I go through them, keep what I want and turf the rest.
