You can get penny prints from Snapfish.
April said that when you add in the tax, cheapest shipping option and penny cost . . . it works out to 8¢ per print!
Use code: STARPENNY (expires 12/14/13)
Excludes: deco prints, collage prints, Disney themed products
You should be able to use the code more than once, placing more than one order, if you desire.
I believe you also get 20 free prints if you’re a new customer. You’ll have to play around with that. I’m not sure if you’ll have to order those first, separately or how ti will work.
Here are a couple other offers they have going on, though I don’t know shipping costs:
