Consistent Computer Bargains is where we got ours also. There was an option to not purchase 5 licenses if we wished we could have gotten "blanks" for about 5 or 10 bucks each I believe. And if we want to add more licenses we can for 2 or 3 years I think. They are really nice to deal with and it was not complicated to qualify for nonprofit. is the email of the person I personally talked to there.
