My original ones were from Office Max, a not so great picture of Elka laying down on a white background. Thin paper. Little information, just my name and email address (no phone number. I'm running a blog, not a "please call me" business).
My newer ones from Moo.com, though, are beautiful. I've gotten them twice now, the first time on their heavier paper, the second time on recycled. Fabulous paper quality both times. When I got the cards on recycled paper, the box was too, which was a nice surprise! They also ship quickly.
The first time, the cards were free because of a Klout.com perk, and so had to have the Klout icon on the back. Oh yes, the back. Moo.com cards let you put a picture and stuff on the front and back. Maybe I'll get even fancier next time and do a QR code (or that might be too fancy and not work. I'm never sure what's too far).
(this is the picture I used on the back. I couldn't get a good picture of the card, for whatever reason)
But, if you're interested in your own business cards from Moo, you can use my Super! Special! referral link, which will give me an amount off my next order http://www.moo.com/share/p8cgnn
