30FIRST
This service allows you to print photos directly from your Facebook, Flickr or Dropbox albums without having to upload them to a separate service.
Their current pricing for standard prints is only 6c per print and you also get 40 free credits when you sign up. These 40 credits need to be used within 30 days of signing up.
They also offer a referral program whereby if you get referred by an existing member, you will get an extra 50 free standard prints. Referrals are done by email only so contact me by private message with your email address and I can send a referral. I get a free gift (personalised calendar or mug I think) for each person I refer and who ends up using the service.
