I've made a Infobox_shoptest at the dutch wiki and added 2 parameters:
 * discost - for discounted gold/mat cost, usage same as cost but with opposite Cost template use
 * disc - for discounted gem cost, parameters exch/noexch, buil/nobuil, etc. (template takes the amount from costgem)

See example at the Test page
