Got a free pack of 50 Business Cards from Moo.com, from an offer through about.me. They arrived today, 12 days after ordering. If you scan my QR code on the back of the card using a free QR code scanner app for iPhone, then it will take you to my about.me profile.
Very happy with the quality of them. I've already got some Moo MiniCards and now I'm thinking of ordering some more of the Business Cards, with the addition of my phone number which I mistakenly neglected to add to these before ordering.
