I've just been quoted £1224.30 per processor (dual cpu box) for SQL Server 2005 (this is for SIMS - the vendor can't get 2K licences any more, and they're downgradable).
That seems _very_ expensive given the obscene discounts schools normally get on MS kit.
CALs are 8.41 each, which seems about right?
(now this wasn't my usual account manager and despite my "Are you sure?!!" reactions, she may have fouled up the server pricing).
