Update Product Price in Product Display?

I have Created a custom line item type and a custom display as per Randy's Awesome screencasts.
In my Custom Line Item Type I have added a Radio Button-Type List Field.
I have created a product pricing rule that says "if a certain option is selected add $15 to the price"
Everything works as planned HOWEVER......

How do I get the price in my product display to dynamically update when this option is selected? As it is right now, the newly calculated price is displayed in the shopping cart but you don't see it until the product is added to the cart.

Is there a way to use rules to do this or will this require a module to be written?

Thanks for any help.

Thanks for the reply Randy. I have watched your Coupon tutorial and Yes you are right. It pretty much does what I want.

However There is one thing it doesn't do.
Dynamically update the current price in the product display node.

Lets say I have a product worth 10 dollars. I have 4 radio button options attached to this Product display through the line item.
If option 2 is clicked, I want it to add 5 dollars to the price. So far, this works as long as the product is added to the cart.
I would like the price shown on the product display node to dynamically add the 5 dollars to the price "onclick".
So. Immediately the customer knows how much their product is now that they selected option 2. If they select option 1 again the price shown will update once again removing that 5 dollars.

I hope that clears up what I'm trying to say.
