Gets the maximum stack size for an item from the active merchant.
maxStack = GetMerchantItemMaxStack(index)
- Number - The index of the item in the merchant's inventory.
- Number - The maximum stack size for the item.
This does not seem to work properly as of patch 2.3, and always returns 1 for items that sell in stacks (such as arrows). Try GetItemInfo() instead.
