The sale starts on November 22nd and lasts until November 29th. A great deal for any gamer, especially for ones that have plenty on their wishlist. Speaking of wishlists now would be a good time to place some interesting titles on them so you can be notified about discounts on them.

The best tactic for sale is not to jump on the train right away, it is best to wait until a few days, maybe even until the last 2 days since some games can go even lower on discount in the last days of the sale. Also, there might be also some packages that include games you wish to buy but are packed with other ones in a bundle and even with a higher discount.
So get prepared for the upcoming sale and treat yourself to something nice!
