# Additional usage limits

The following option is added to the Usage limits-tab:

## Limit discount to (PRO)

Easily control which items are eligible for discounts. By combining this feature with a 100% discount coupon, you can create flexible "Buy X, Pay Y" rules. For example, using the "Limit discount to every nth item" setting along with a "minimum matching quantity of products" set to 3, allows you to offer a discount where every 3rd item in the cart is free.

Developers can program additional discount limiting rules by using the `wjecf_get_limit_to_options`-filter.

### One item per order line

Applies the discount to a maximum of one item per order line.

### Lowest priced product (single item)

Applies the discount only to the lowest-priced matching product.

### Lowest priced order line (all items)

Applies the discount to the lowest-priced order line.

### Every nth item

Applies the discount to every nth item in the cart. Note: n is the minimum quantity of matching products set in the Usage Restrictions tab (or defaults to 2 if not specified).

### Nth item onwards

Applies the discount starting from the nth item in the cart and for all subsequent items.

### n Lowest priced products.

Discounts the n lowest-priced products in the cart. Note: n is determined by how many times the coupon applies, based on either the subtotal or the quantity of matching products.
