A common error that Microsoft customers make is negotiating concessions or accepting promotions from the company without recognizing that, in the long run, the customer will still pay for them

When a “Discount” Becomes “Hand Cuffs”

One customer negotiated super pricing on a hosted Microsoft service (also available on premises). including a price cap of no more than 5% on renewal. That’s what the email said.
Unfortunately, that’s not what the contract said. The actual contract terms said the price would not rise by more than 5% on renewal of their full Enterprise Agreement.  

That’s right. When they accepted the price cap “concession” they had just negotiated their next EA. At full price.
