Which item you would never buy secondhand?
From what things you can not understand that other people buy it secondhand on, lets say, Ebay or Craigslist (or similar sites in your home country).
And that same item, would you feel ashamed, or not, to put it for sale on those sites.
My girlfriend suggested some months ago to buy a secondhand mattress, but that is something I would never do.
Wouldn’t put it for sale either.
