Today, when you order "Haunted Deck Bicycle (Red)", you'll instantly be emailed a Penguin Magic gift certificate. You can spend it on anything you like at Penguin, just like cash. Just complete your order as normal, and within seconds you'll get an email with your gift certificate.
You don't really need instructions for this, the gimmick itself should explain everything to you.
However in my opinion the gimmick is fiddley and gets in the way, the device requires quite a bit of
settup and there are much easier ways of acheiving this effect; Loops for instance.
