I tested this out and shipping for 60 prints is $3.74 so- .06 per print. I think that is a great price for prints and even more so since they come straight to your door.
I did test out less prints if you don’t need 60:
45 prints = $2.99 shipping (.07 per print)
35 prints = $2.49 shipping (.07 per print)
30 prints = $2.24 shipping (.07 per print)
