Amazon currently has deep discounts on two Xbox One games in both disc and digital formats. Halo 5 Guardians and Quantum Break.

Halo 5

343 Industries's sci-fi shooter Halo 5 is currently discounted by $30 down to $29.99, again in both disc and digital formats. Quantum Break, the recently released action game from developer Remedy, is discounted $20 to $39.99 with digital and disc formats. It's rare that a game gets such a price cut in both physical disc and digital download formats. There's no word on how long these discounts will last.
