What you're talking about is volume pricing. That doesn't require any discount or any coupon setup. Just set several prices with a minimum quantity in your products, like damendieta explains.
Is there a way of applying this to all products easily. Im selling lots of different digital prints. Each print is £15. I want to apply a volume discount to all the products but as I have over 200 different prints this is going to take a long time unless there is some way of applying the discount using a bulk action.
