I don't want to use coupon code block on cart page so I delete the code on this file
block type="checkout/cart_coupon" name="checkout.cart.coupon" as="coupon" template="checkout/cart/coupon.phtml"
This update works, there is no coupon code on my cart page, but if there is two or more items and I delete one of them, the discount code block show again and looks weird
After delete product
What should I do the cart page work well after delete product?
is there any other way to disable coupon code which don't make this problem?
