Thread: Add price column to shopping cart page - V7

I need to add a price column on the shoppingcart.aspx page when the products in the cart are listed. Cuurently, it displays the product, the quantity and the final price, and I'd like to add an additonal column to display the price [per unit.

Where would I need to make such a change - in the xml package, code behind file, or somewhere else?

That would be a source code change, in the ShoppingCart class, DisplaySummary method.
