FreePrints is a new iPhone app that will let you upload images from your camera roll and have prints delivered to you. The service offers up to 1000 free prints per year for 4×6 prints. Other sizes like 5×5 (for Instagram) are available for a cost. Shipping starts at $1.99.
Most of the reviews thus far on the iTunes App Store are glowing on both the quality and reasonable shipping costs. And, of course, the app is a free download as well.
FreePrints sounds like it might be a good way to get some of those images off of our iPhones and into printed form. Check out FreePrints here on the iTunes App Store.
