As seen on the Ellen Show recently, there will be 100,000 free $15 gift codes released each week until November 13, 2009 for the Kodak Gallery store. They have a ton of items for under $15, so if you shop around, you should be able to get something for free.
My mom is probably sick of all the photo albums I've given her as gifts over the years, but too bad! They're full of happy, loving childhood photos of me and my siblings and she's gonna have to cherish them whether she likes it or not!
