I need to add a coupon code and apply a discount for against only one item in cart
I need to be able to add a coupon code to my cart and have a discount applied only to only particular item's value in the cart....so if the customer adds two $10 widgets to the cart and enters a correct coupon code which is worth 50%, the value displayed and charged for that line item would be $10, one widget would be $5. I don't want to give a discount for the entire contents of the cart, only that one item number. I took a listen to the tutorial and looked at the recipe, but don't see how to implement for one item. Attached is what I have so far.
