IEEE Computer Society Invitation

Few weeks ago i created an account on IEEE and today i got the invitation to join IEE Computer Society. They gave a discount US$90 if i'm willing to join before the end of this year (31 Dec 2007). I will think about it first, as the rate is quite expensive (for me). Personally, it's very interesting, since i can get access to more than 1300 courses and also got IEEE magazines, etc. I wonder if my campus has already subscribe to this community or not.
