I recently ordered a free sample set of 10 green business cards from moo.com! I've always loved their quality of work and unique products. You can give them a try here: http://us.moo.com/partner/sample/ Because they are free, their watermark is placed on the bottom left corner.

Shipping is also free! I received my business cards within 3 days of placing the order! They also provide you a USPS tracking number too.

There are two options of cards: classic or green. Of course, I went for the green! Green cards are 15.5 pt, light coating, and non-reflective. They are also 100% recycled and produced using wind power. The classic come in 16 pt, matte laminate, silky and faintly reflective. They are sourced from sustainable forests and are elemental chlorine free.

I really like the thickness of the cards. At the same time, the cards are super smooth. The ease of placing my order online was so simple. I connected to my Flickr account and was able to pull up my personal photos to be printed. So easy! The quality of the photos on the card are exceptional.

On the back, I just printed my contact information and website. They offer about 10 different font styles and they're all easy to read and modern.

I would definitely use them for future prints, like postcards. I love their packaging too!

You don't see 10 cards because I gave out 4 already!
