title: How to allow Magento coupons in checkout
body: <p>I'm able to create coupons in the backend however in the checkout process, the option to enter a coupon is not there.
  The only other information I can find on this is how to disable coupons by commenting out the line </p>
  
  <p>block type="checkout/cart_coupon" name="checkout.cart.coupon" as="coupon" template="checkout/cart/coupon.phtml"/</p>
  
  <p>in the file, </p>
  
  <p>/app/design/frontend/base/default/layout/checkout.xml</p>
  
  <p>I've checked that location and that line is not commented out. </p>
  
  <p>I'm using Magento community 1.7.0.2</p>
