Don't really understand why you would do this. Why didn't you wait? The season pass doesn't cost any more now than it did at release, and you didn't save anything by buying the deluxe edition of the game. If you bought the retail version you had no choice, I guess, but if you bought the digital version there was no reason to buy the season pass before you knew what it would include.
In a similar situation, except I was able to pre-order the Deluxe physical version for $34 (instead of paying $40, so I figured it would be a deal based on previous Trials HD and Trials Evolution DLC).
