I love Vistaprint. I got all my business cards, magnets, stickers and paper pads there. You know whats cool about that site that you can do for free
... I made a business card that turned out super cute on the website using that option to build it on there, and then when I was done, I copied & saved the picture of it in my Mac (by using "command+shift+4") instead of ordering it... And now I use that picture in some of my ads on Craigslist and other sites. It turned out really cute and it was a sneaky free way to make a cool ad.
