I will reiterate what I said posted on Steam. Because the Year One Pass is on sale, it is the cheapest way to get Season 3+4. Even though I already purchased the deluxe edition of the game and already have Season 1 + 2, because Season 3 + 4 are not discounted on there own, it works out ~40% cheaper to purchase the pass than the individual 3 + 4 DLC. You will not get the 1 + 2 content again and there is no further discount off of the pass if you have it. However, this is the cheapest way to get 3 + 4 seasons, and it is the cheapest it has ever been. So thanks I guess codemasters for the sale, don't know why you couldn't just have discounted the standalone 3 + 4 seasons by 40% as this would have prevented any confusion.
