I printed samples on Moo.com. They give you a free sample set, but you have to pay for the shipping. The sample cards have a bar across the bottom of the photo side with a Moo promotional code. The quality was good enough for me to order a normal set last week, but it didn't blow me away.
- The thickness of the paper seems to be enough to last a while in a persons pocket or wallet.
- The ability to print up to 50 different photos is awesome. I meet someone who wants wedding photos, so I give them a wedding sample shot. I meet someone who likes pinup photos, so I give them a pinup shot. Etc.
- The photos come out with a matte look (not like glossy film), so it won't always present your work in the best possible way. I'm also not confident in the color being accurate due to the printing process and paper that they use.
- Price is very fair for being able to have 2 sided business cards with 50 unique photos.
