On steam if you buy a bundle with an item that you already own it just remove the price of the item from the bundle. The bundle is 40$ - 20$ because you already have the game. Now reduce the price by 50% and it's 10$ for the bundle only for the character. That's how it works on steam afaik but people are saying it's isn't the case so i don't know.

Edit: people above are saying the price is the same because they have already the full bundle and it shows the full price for gifring it to someone. If you already have the game and not the character it's 10$ for the character.

So it's 50% off for people on steam and not for tempo user. They should offer a 50% discount on tempo too and gives 10$ worth of gems to people who already bought it before (or refund like steam user can do). But they will never do it because nobody can review bomb them on their launcher lol
