How much profit is okay when selling used stuff?

Morality is not about the percentage of profit you make, it's about being honest about the product you resell. If the product in question is in good condition, then there's no problem in selling it for the normal going price. But it would be morally wrong to knowingly sell a defect product for that price.

I agree of course. I'd never sell a defect product, or only when stating clearly that it is defect.

Thanks for all the opinions so far. It really means a lot to me.

Especially Rol's comment makes me feel good, as am always honest about the stuff I sell. (I also take lots of pictures, so it would be hard to sell stuff that's in bad condition. ;)

I also collect retro games, so I know how important it is to be honest about the condition of something.
