There is no coupon code. You are automatically given free shipping with orders over $75. I think the only thing that doesn't count towards free shipping is the large guillotine cutter because of how much it weighs. Also, pay attention to pre-order items. An order won't ship until all items are in, so if you have a pre-order item in your purchase, you'll be waiting until it arrives for everything...so order pre-order items separately. Hope that helps....
