You can get 50 Free Facebook Cards for a limited time from Moo.com. I just ordered mine today and can't wait to get them. How it works is that you need to click this link and Moo will ask to access your Facebook account. It will then pull your timeline cover photos for the images of the cards. You can make cards from either your personal account or your business account.
Unfortunately for me, I had a lot of timeline cover photos with text, so they didn't work as the text was cut off on the sample image. I then ended up uploading a few more photos and creating new timeline covers so that I could have more options for these cards. I apologize to those of you who received the the flood of timeline cover updates in my Facebook stream.
Once your images are uploaded, you can customize the contact information on the back of the card as well as add a message or favorite quote.
Here is one of the cards I made.....
Even though you can't fully customize these cards, I think they are worth grabbing since all you have to pay is shipping (for me it was $5.50). Such a deal!
