In order to get the price.
You use the code OTTER10 for 10% off,
BUT at the bottom left it says "GET $10".
So click on that, put in some phony name and e-mail, after that you got to share to a friend. Click on Share via Link, and then open a different type of Browser and paste the link.
That link will take you to a new page and then put in another phony e-mail, and you will have the coupon code for $10 off.
The coupon stacks, so I used the OTTER10 and my coupon code.
