Just found this deal out.
Put 100 4×6 pictures in your cart (need 100). And then checkout using the code WEDPRINT. Probably only works today.
Totally works I just did it. My total was $1.06.
IF YOU HAVE PREVIOUS CREDITS IN YOUR ACCOUNT, YOU MUST USE THEM TOO IN ORDER FOR CODE TO WORK. (SEE COMMENTS)
I just bought 100 photos a few weeks ago, I like to keep some permanent ones around for photo albums someday…
