Yes, it seems to be a very lucrative business, doesn't it?
One thing I neglected to mention before is that if you have used a particular reseller in the past (whether buying or selling), make sure to inquire whether they offer any discount for "repeat customers". Because we have done business with both of the above resellers, they are offering us a 1% discount on their sales commission to sell one of our contracts. 9% isn't much different than 10% but I'd rather have it in my pocket!
