Checkout as you normally would when purchasing a product on Amazon. On the last form before submitting your payment there will be a box that allows you to add a discount code. Simply copy and paste the coupon code provided into that box. When we email the coupon to you we also include more detailed instructions to make the process really easy for you.
If you are an Amazon Prime member or your order is above $25 then you qualify for FREE shipping. Also, any item with "FREE Shipping" messaging on the product detail page, that is fulfilled and shipped by Amazon, is also eligible and contributes to your free shipping order minimum.
