Just a heads up, they charge $1.99 per roll shipping and handling. So, it would cost $4.98 to develop each roll. Still a good deal. I always used York Photo for film developing years ago when I still had a 35mm camera. I probably still have some of their mailers around. If you are going to mail your film off for developing, I would suggest you put your name/address on each roll of film. I always used self stick address labels.At snapfish, its only 2.99 a roll and you get a discount for over 10 rolls. They also pay for the shipping for you to send it in.
