If you go to SaveMore Daily you will get $10 in FREE credit! The Pen is $8 so it will be free. You do have to add a CC, but it won't be charged, and they will NOT automatically send it to you, you are buying a voucher, so you'll have to go back in a few days to get the voucher and redeem it on the Whitening site. If you have any questions, feel free to ask.
