STEP ONE: Start at Ebates and use their link into Buy.com. If you do not have an Ebates account then you will get $5 when you sign up, making the humidifier only $4.89!
STEP TWO: Search for 00316 and the personal humidifier will come up. Add this to your cart.
STEP THREE: Checkout! They also have a deal where you will get $30 free if you sign up for their credit card. That would make this product (and $20 more) free.
