If you liked the idea behind previously mentioned Google Me business cards but don't like paying for things, these 25 free biz cards are just the ticket. The business cards look like the screenshot here, courtesy of Gizmodo's Jason Chen. Unfortunately when I tried following the "Order profile business cards link" on my Google Profile page, I was met with an Invalid Offer message, so your mileage may vary. I'm guessing that you need to have entered enough information on your profile so that it's eligible to be featured in Google search results before you can order the business cards, since the whole idea is that Googling your name will get you to the profile page.
To get your cards, either sign into your Google Profile page and look for the Order profile business cards link or, assuming you're already signed in, you should be able to follow the link below. Thanks Jason Chenzmodo!
