Details
itemIndex counts into the number of different "alternate currency" tokens required to buy the item under consideration. For example, looking at the 25-player Tier 9 vendor, a chestpiece costs 75 Emblems of Triumph and 1 Trophy of the Crusade. This function would be called with arguments (N,1) to retrieve information about the Emblems and (N,2) to retrieve information about the Trophy, where N is the index of the chestpiece in the merchant window.
Most vendor items only use a single type of alternate currency token, so itemIndex will typically be 1.
itemIndex should never be larger than the itemCount returned by GetMerchantItemCostInfo.
