Options - Buy Another Theme, Repeat Discount?

[D12]

I purchased one of the classic themes and was very happy with it (Magazine), it has served all of my needs and then some.

I tried to upgrade it to the new genesis version and the layout was a little glitched up so I decided to leave it as is for now.

Here is my question, I am starting a second site related to my first (this one is a paid site). Here are a couple of options I am curious about:

A. If I want the same look with some customizations, can I use the same license for the second site at no extra cost?

B. If I want a different look (most likely scenario), do I receive a lower price on one of the new Genesis themes because I am a past customer and, if so, how do I make that happen?

Thanks for a great product!
