How it works is just click on the BUY icon and because you are logged on to your account when on this forum it will automatically show you your price.
There used to be a different system on the store site that had "upgrade" buttons but now it's all linked to your account.

Our e-commerce partner, cleverbridge, uses registered products in customers’ Cakewalk Single Sign-On (SSO) account to determine upgrade pricing.
Your upgrade pricing is displayed automatically on
the Cakewalk Store.
If the Cakewalk Store does not display proper upgrade pricing, make sure that you have signed in to your Cakewalk SSO account
prior to visiting the Cakewalk store. Your Cakewalk SSO account must contain qualifying products in order for the correct upgrade prices to be available to you.
If any qualifying product is missing, please click the
Feedback link in your Cakewalk SSO account to alert our database team. Supply as many details as you can about the missing product(s) to help us add it to your account as quickly as possible. Once it is in your account, you will see upgrade pricing on the Cakewalk store.
