Here's another way to use your $10 Save More Credit (you get it when you sign up). You can get a Smiling Bright Teeth Whitening Pen for $8.50! SO FREE with your credit plus $1.50 for another purchase! It will also ship for FREE. I looked up Smiling Bright and it has good reviews, but I couldn't find a specific review for the pen. Anyone use one before? Here's some info on the pen.
