The GameStop ad for Black Friday 2015 has leaked. Twelve full pages of deals and specials have been revealed, including savings on gaming console bundles including Microsoft's Xbox One and Sony's PS4.

The bundled deals offer $50 off the retail price of Sony's 500gb PS4 bundle, with a price tag of $299.99 and Microsoft's 500gb Xbox One Gears of War: Ultimate Edition bundle, also priced at $299.99. Other Xbox One Bundles are also available for the same price, including the Elite bundle.

The pricing is in line with other big box retail outlets who are offering pre Black Friday savings or whose ads have leaked online, and while the bundle deals are good, some of the stores whose Black Friday sales have not yet been revealed may offer even better savings, or may offer an additional store gift card in addition to the $50 savings.

The GameStop pricing on pre-owned systems is definitely worth taking a look at if you're interested in an older Sony, Microsoft or Nintendo product. The original Xbox 360 or 80 GB PS3 and 3DS are all going for $79.99, and $99.99 will land you a 3DS XL. The real savings kick in if you buy any two of these systems, because GameStop is throwing in another additional system absolutely free with the purchase of two.

This could be a great deal for parents who want to buy gaming systems for several kids at once without breaking the bank, or for several rooms in the house. Just be sure your kids aren't going to whine and complain that all their friends have the latest and greatest Microsoft or Sony console while they have the older version--it may not be worth the savings.

Of course GameStop has great discounted prices on a slew of gaming software and accessories, and you can check out the full Black Friday ad in its entirety. GameStop had previously announced that it would not be opening on Thanksgiving Day this year, so the in-store bargains are set to kick off on Black Friday itself, Nov. 27.
