Moo Cards, but we're also fans of their customizable greeting cards. Our favorite thing about them is that you don't have to choose just one image to print - you can choose up to 10. If you don't want to send photo cards, you're sure to find images you like among their many designers.
Once you've selected your photos, choose your font, colors and layout. Moo Greeting Cards are currently on sale - a box of 10 for $19.99.
