So I got ripped off

I was at a local brick and mortar to get an Invisible deck, and while I was looking around I found a trick called "Where's the penny?" for about four bucks. I figured what the hell a new secret for four bucks. I got it along with the Invisible deck and a new silk. Once I got the chance to check it out in the envelope was two weird backed cards, a penny and a dime attached to each other a few inches of invisible thread and a 3" by 6" piece of paper with "instructions" So here's why I'm mad its not the cheap gimmick its that after reading the piece of paper three time I still have no idea what the heck I'm supposed to do.
