I can't give a separate id or class to each area underneath the product
You have to have a product id to find your inventory in a database. Use that number for the id or, if you are going to use it elsewhere as an id, it is very easy to make sub id's by adding to the main id. LIKE: product id is 123456789123 and the id of the price div 123456789123a3
All price div id end in a3. Understand?
