New Official Rubik's Cube. Cleanin out my room!

Hey guys, I'm cleaning out my room and I found a new Rubik's Cube that was never opened so I decided to put it up on ebay. This is my first time selling something on ebay, (I've bought stuff) but if anyone can tell me how to edit the paypal invoice to give CAG'ers 10% off I will. Thanks and BUY IT!
