EBay

eBay is a web site in the Movie continuity family and (incidentally) in the real world.

If you're a young teenager looking to score some cash to pay for your first car by hawking your great-great-grandfather's junk, eBay is a good place to do it.

Unfortunately, killer alien monster robots can also use it to track you down.
