Design Pattern Framework License Renewal and Discount
I had previously purchased the .NET 4.0 Design Pattern Framework and would like to upgrade to the 4.5 version. I can see the upgrade cost for me would be $59.

Our website does not support this offer yet (we're working on it). For now purchase at normal price and then send an email to email@example.com. We will then refund the $20 discount back to your account.
Hope this helps.
