make sure that the recordset that is performing the price lookup is before the cart update code. 
Originally, the update behavior was at the very top of the page (above the html), I moved it down below the recordset, which is in the <body>. Now clicking the "Update Cart" does the same thing as before, except that you have to click it: FIRST to POST the newly selected option, AGAIN to update the price increment of the specific product and AGAIN to update the Grand Total.
