Hi Jason,
Great question!
Your other expired license isn’t unlimited, it’s an agency-level license key which normally sells at $299.00. When users upgrade from one tier to the next we’re happy to only charge the difference between the cost of the two tiers – as a thank you for upgrading – and in this case that’s $449.00 (adjusted slightly).
In fairness to users who don’t quite catch the fact that their license has expired, we also offer this pricing to users whose licenses are no longer active.
In your case, then, you have a choice as to which path you follow and in terms of offering you a discount, I couldn’t offer anything lower than the agency-to-unlimited path that is open to you 🙂
I hope that answers your questions, but do let me know if I can clear up anything else.
