If you are a Shutterfly customer, you may want to check your email inbox. Today I received an email with the subject “Thanks for choosing Shutterfly | Enjoy $20 just for you.” It includes a one time use code for $20 off your purchase of $20 or more. The credit I added to my account expires on 1/18.
Right now get free shipping on orders of $30 or more with the code SHIP30. You should be able to combine both offers and get a sweet deal on a Shutterfly product.
