Remove coupon box from Checkout page

Q: I’d like to keep the coupon entry box on my CART page. But I’d like to remove it from the CHECKOUT page only. It’s a bit confusing to have it on both pages. Is there a hook or something I can use to remove it on the checkout page only?

A: You need the code to override the frontend.css in Jigoshop:

 form.checkout {visibility: hidden; display: none;}
