I guess this information will be usefull : everyone is able to get SA two license keys for the price of one.
Since Jule(2009), after purchasing the first SA license key, we send the second SA license key free of charge. Since the most part of users, as a rule, have two working computers.
I'v decided publish this information in my blog, because still most of people do not know about this ability to get 2 keys for the price of 1.
Sincerely yours, Maria and MSM Group.
