Flag allows anyone (within the US to start) to print and mail a pack of 20 photos each month for free. You can keep the prints yourself, or send them to the people you love. If you want more than 20 a month you can buy as many as you need.

To make photo printing fun – for the first time by our reckoning – we’ve designed a photo finishing system ready for the 21st century. Museum quality (Giclée) printers, German 220 gram photo paper from sustainable sources, laser cutters, and robots with carbon fiber arms will allow Flag to deliver prints, for free, that are better than any you can pay for today. We want to turn your memories into mementos you can be proud of.

Our secret to making photo printing free? An advertisement on the back of each print. It will always be tasteful, and we are steadfast in our commitment to never sell or share your personal information with advertisers.

This is something I would use. I’m okay with an ad on the back of the photos. Samuel Agboola really came up with something interesting here.
