Multiple order discounts?

I bought object desktop (great stuff).  I got FENCES with my purchace.  I originaly didn't have a use for it on my new PC, but I did on my older one.   Not being 100% sure I installed the demo on both.  I have not entered my key on either yet, but I now feel the need to have it my new PC.

Can I get a discount on a second licence to the same software I already bought?  I know it's like $10 for a new key but after paying for the full suite, it's a bit steep.  Even a few bucks off would help. Does Stardock have such a policy?
