Have you ever purchased anything from us in the past? If so you could be eligible for a discount. We used to sell them individually CSS Sculptor $99, CSS Menu Writer $99, Site Sculptor $149... so you are looking at a total savings of $50 and a loss of the functionality of the other 6 included extensions.
We don't offer them individually any more, but give our sales line a call and we can look into your purchase history and see if we can do something for you.
