Buy one get one half off

With Hikashop Essential is it possible to set up a simple Buy One Get One Half Off on a product? It seems in the Discount area you can only apply a discount to a single product or category and not to multiple product discounts. Am I missing something?

you can do that by creating a coupon with the "auto load" option turned on so that it loads itself in the cart during the checkout.

Discounts can be applied to multiple products. Simply create an unpublished category that you set in your discount and add it to the products as a second category.
