Behind the scenes

 * While the website shown on-screen in Random Shoes was identified in dialogue as eBay, it did not match eBay's real-world appearance.
 * After search-wise.net, eBay is the second website portrayed in televised Doctor Who Universe media which actually exists on the Internet, and was not put online as a marketing tie-in by the British Broadcasting Corporation. It is the first real-world website portrayed performing the function it does in reality.
 * According to the pseudo-narrative — and therefore invalid as a source — Torchwood website, Dogon sixth eyes began appearing on eBay after the Battle of Canary Wharf, and became very popular in Belgium.
