Right now, you can get a 5x7 photo card from Shutterfly for absolutely free!
First, follow Money Saving Mom's directions on how to get free shipping for you when you send a special gift offer to five friends! Shutterfly will then e-mail you a special code for free shipping off their entire site.
Then, design a 5x7 photo card, either flat or folding, and enter the code CARD4U at checkout.
Your card will be sent to you in 3-5 business days!
Personally, I made an adorable Christmas card with my baby girl on the front... now, I just need to figure out who will be the one lucky recipient!
