URL Question

Hi Guys!

I am doing some PHP work for a friend and he's been using CS Cart. Is there a way to phrase a variable for a product cost? For example, let's say I want to make Product ID #11 be $100.

Such as http://blah-blah/index.php?dispatch=products.view&product_id=11&price=100

My other questions is can you eliminate the AJAX form and replace it with your own if you modify the smart templates?

Thanks for your help!
