Product quantity discount
Hi,
Im trying to have my cart discount a products subtotal if they have more than 10, 20 or 50 of that specific item in their cart, it doesnt matter which item, it is the same for all items. but i cant seem to find one of the options in the discount drop down for how to do this, it wants me to enter a specific item ID in rather than have the discount function for all items.
How can i do this
