Once you get to the site, click on "Shop Now" and select the cover or gifts set you would like. At checkout, type EXPECTING into the promo code box and it will bring the total for your UdderCover to $0. All you pay is shipping fees. You can use the code more then once just open up a new browser.
The covers are normally 32.00 plus the Shipping is 9.95. I have one of these already and love it.
