Amazon Prime is generally known for a few things. It’s a way to get great, free shipping and access to on-demand, Amazon Instant Video. But now, it’ll also be known as a means of getting day-one discounts on video games. People with a membership will get 20% off of new games.
There’s two ways to get this Amazon Prime discount. One is to place a pre-order. However, it also kicks in if you buy a new game within two weeks of its launch. This combines with free release day delivery and a pre-order price guarantee that ensures you pay the cheapest price for a product.
This should automatically extend to all pre-orders. However, if you want to double check, you can contact Amazon support and have them make sure any game pre-order you’ve already placed has 20% taken off of the price.
