Product options have the same properties as Products with the exception of the volume discounts which cannot be assigned (as well as discount coupon) to a product option.
On contrary with the product price, the product option price can be negative. The product option price is the amount that is either added to or subtracted from the given product price. The product option is sold as an addition to the given product, not as its replacement. If certain discount level applies to the given customer, this discount level applies for the chosen product option as well.
