In case you missed the announcement at the 2008 Microsoft Worldwide Partner Conference...

All qualified partners (i.e. Certified, Gold, and SBSC Partners as well as partners who have signed a CSA agreement) can now deploy CRM Online for their organizational use for $19/user/month – about 66% off our Professional Plus package.  Plus there are no strings attached – partners can cancel at any time, and early termination fee will be waived for partners.

(This program will be available to partners in Fall 2008.  Other important offer details are listed on the URL.)
