My dad really likes Griot's, so I am going to get him something from there. I looked on the net but could not seem to find a valid discount code. Does anyone know one?

Just wondering if anyone has used this kit, which consists of the spray wash and what looks like very nappy towels. With the temps lowering quite a bit, I was going to possibly pick up a kit, hoping scratching won't be an issue. http://www.griotsgarage.com/product/11347.do
