I don't know about others but I have found it very difficult to recieve credit from Snapfish. I was using them long before I found sunshine rewards. Originally they did not let us know that prepaid prints are not included (Trish learned this after I filed 2 different trouble tickets on 2 different orders) and then I ordered our Christmas cards through the link and never received credit for those either. I love snapfish and have recommended it to many people - but I wouldn't recommend them for the credits here.
