Here is what it says on the Snapfish Facebook page:
Spread Some Snappiness by celebrating the people who’ve inspired, helped or delighted you in 2010. When you share a special photo and add a wish or a thank you, you and 5 friends you thank will each receive $5 to spend at Snapfish.com! We will also make a $1 donation to the Make-A-Wish Foundation® for every person that shares a photo. Click the Snappiness tab on our Fan Page to start Spreading Some Snappiness now!!
