This reminds me of the latest version of Diablo II. With the implementation of 'synergies', becoming proficient in a certain skill will slightly increase the power of similar skills.
Or in the expansions of NWN, where many of the thief skills are synergistic, or like listen, search, and spot, where if you take one skill, it provides a bonus of +2 to another.
Just order from Newegg.com. If you're in the US, you can get it within 48 hours (sometimes 24). Anywhere else in the world it might take a little longer, though, but at least it would be on its way and you would know when you are getting it.
