Below is an example of the basket contents section of the BASK page template.  This process loops through all 
the products in the basket and updates the quantities up or down and deletes those marked for deletion.  We 
have found issues with some discount modules, including our coupon module, with this process.  You should be 
using the latest version of discount modules which show discounts in the basket.  You should also thoroughly 
test those modules in this basket one click update environment to make sure there are no issues.
