A DON'T PANIC Limited Edition Bundle?

I'm posting to see if anyone would be interested in purchasing a Don't Panic Limited Edition Bundle. There would be a limited number available and the bundle would include the following: 
  • A signed paperback
  • A special Don't Panic bookmark, which will only be available via the bundle.
  • And either a keychain, a tote bag, or a magnet. (I haven't decided which will be included.)
I've included an image of the keychain, tote bag, and magnet at the end of the post. The bundle would cost $10-$15, plus costs of shipping and handling. This post is only to gauge interest. That said, if you would be interested in purchasing a bundle should it become available, please fill out this form. Thanks!
