Please disregard coupon, I received this email from Jandd:
We are a small company and can only hand out a certain amount of coupons based on our dealer inventory and stock. Please update your post to let people know they need to sign-up through the newsletter (Homepage left column) or when they warranty an item and opt in for the email to get the coupons.
