I upgraded from Trello free to Trello Gold just 2 and a half weeks ago and I paid for the annual subscription.
Now I am thinking of upgrading again to Trello Business Class but I don't want the money I paid for my Gold subscription to go to waste. I am very eager to upgrade to Business Class but not if it means to pay the full price again. Is there a way to upgrade to Business Class without paying the full price since I have already paid for Trello Gold and I want an extra upgrade now?
