Chris sent in a link to Play.com’s listing for the Blu-ray Ghostbusters disc – turns out, they’re giving away an Ecto-1 keychain, the same item given out at various press events in previous months, as well as Amazon.com exclusive Slimer Edition. As it’s not certain is Sony will be selling the collector’s editions planned for North America, in the UK, this could be a good way for British collectors to get some bonus Ghostbusters swag.
