How can I add Discount for more than 5 items?

Hi

We already have a 20% discount applied to our goods on our website. Is it possible to add a further 10% discount for orders of more than 5 books? And if so, how?

Please advise.

You can create a coupon which would auto load during checkout. You can restrict that coupon to a minimum order amount. You can't restrict it to a minimum number of items in the cart.

OK, how? In the discount section I can only set 10% and the code name.

You need to select the type coupon. That will display the auto load option as well as the minimum order price (it's in our commercial edition).
