I work in the print industry. I just want to point out that even if someone scanned in their card and emailed it to you so you could print it...most likely it would not be accurate. Those cards are most likely printed with specific PMS (pantone matching system) colors, and not 4 color process printing. Even if they managed to scan it in perfectly, which is unlikely due to calibration issues and automatic color correcting software embeded in most scanning software, your average printer will not be able to accurately reproduce the exact colors on one of those cards. At best, it would be a "good enough" situation.
Your best bet would be if someone has an extra one they could send you, from buying the master kit more than once.
