Amazon’s photo printing service is running a promotion where you can get 100 4×6 photos printed for just $1. If you’re a Prime member, you’ll also get free delivery. Just select the prints you want and enter PENNY100 at checkout for the discounted price. If your photo’s are already stored in Amazon Drive, you can directly select from photos you already have uploaded. Otherwise you’ll need to upload the photos you want printed.
