Buy to Save Money Right Now
If you do decide to pull the trigger, you can save some money by ordering from Best Buy. You don't need to wait.
You can save some cash if you're a Best Buy Gamers Club Unlocked (GCU) member. Best Buy has shut down the GCU program, but those of you currently in the program can still take advantage of the deal.
If you don't want to deal with either of those consider buying the game at Dell. The retailer is offering a $15 eGift card with any PS4 or Xbox One order.
Rockstar's also released a Red Dead Redemption 2 PS4 Pro bundle that comes with a console and a copy of the game for $399.99. This means you essentially get the game for free. The bundle is available via retailers like Amazon and Best Buy.
