The only "extras" I sometimes get is the occasional free game thats included inside systems I purchase off of craigs list or Goodwill. As for the ants, I agree that it wasn't the sellers fault. Sometimes these things just happen.

In high school I remember me and two other students grabbed a bag of dorritos out the fridge to eat. Right after we poured our dorritos on plates, we noticed a roach limping out the bag(even extreme cold can't kill those bastards). Luckily nobody ate any dorritos before we saw him because I would have puked right there
