I have essentially a shopping cart with a list of products and their costs. I will be adding and removing products from the list so I'll need to have line item events. I'll also need to have a total line that will need to be updated as products are added/removed (see example below).

Does anyone have any design suggestions? The total line is tripping me up. in advance. /Greg

Product A      $1.00
Product B      $2.00
Product C      $3.00
Total            $6.00
