PowerStore Multiple Item Discount
What is the best way to give a multiple item discount to one product in powerstore? I want to lower the price each time a higher quantity is submitted for a particular item. For example if the customer buys 1 the cost is $135. If the customer buys 2 the cost is 130*2 or $260 total and so on when they buy 3, 4, and 5 items.
Thanks.
