customers receive 10% off your entire order when you purchase 4 or more items…
but…
we need the discount to be applied to each individual sku's price, not the row total and/or order subtotal.
Currently when pulling order info, magento shows the full purchase price of an item and will apply the discount to the subtotal of the order.
Alternatively, applying a "catalog price rule" when you purchase 4 or more items would probably work.
