When you make your pre-order, we will reserve a code for you in our system. This is also when we process your payment, so it remains the final amount you pay regardless of any future price increase.
The pre-order keys are delivered on the date and time that the game is officially released, which is also the date mentioned on our product page.
Please note that official pre-order bonuses or any additional content may not necessarily be included unless they are clearly mentioned in the product description on our website.
