Use the code PRINTS for 101 free 4X6 or 4X4 prints and also 1 16X20 print and 2 8X10 prints
To save on shipping, order 100 prints rather than 101! You can see the shipping charges depend on how many prints you get and if you get 100 its at the top of one price point, where as 101 prints is at the bottom of the next~ this might save you $1.
