I just do not see the point in people doing this. It's not like the Halo console offers you anything, like sex for instance, over what you have now. Heck, the new consoles are not even better / more efficient than the originals from two years ago. Not like you are getting an Elite Controller or anything special with it to justify this. Just a console with a paint job and maybe a controller with one. That $100 would be better spent getting a 3TB drive to connect to it to have more games readily available. If it is $300 that is just like lighting money on fire stupid. Yes, I'll say stupid in this instance.
I also think people are ignorant if they take the GC off the price they are paying. It doesn't work like that and never has. It simply means you are paying retail but getting an extra $50, not taking $50 off the price. So it would be $550 worth of stuff for $500, or in this case, $610 worth if you take a $59.99 game as well. Still paying $500, just the perceived value of what you get for it. If that doesn't make sense, go into (almost) any new car dealer and say you will pay MSRP if they will give you a $500 gift card for accessories or services (like oil changes). With few exceptions you will be handed a sheet to sign for full MSRP and stating you will get a $500 GC. Does that lower your total price or did you just pay MSRP?
Not picking on the person I quoted, just laying my opinion out in the first paragraph and facts in the second.
And I think you're ignorant to the situation, in some respects. For starters, a 3-TB external is overkill for me. Throwing $110+ (because I'm not buying some junk Toshiba drive) at that solves nothing, really.
With the Halo 5 console, I get the HDD upgrade from 500 GB to 1 TB. I go from an original controller (which is occasionally squeaky and has something that occasionally rattles inside--meaning I have to make sure it's not doing that during the trade) to a new Locke controller that I was going to buy (I want to own both Halo 5 controllers). It also comes with the $100 LE of the game. So, right there, I was going to spend $80 (after GCU) on the game and $70 on the controller. That's $150 I was spending, no matter what. Then, I get a free game with my purchase, and so that's another $50 I was going to spend anyway. I also get the $50 GC to essentially get another game free, which I was going to end up buying.
I was going to end up spending $250 on 3 games and a controller regardless. With this trade deal, I'm essentially getting a free console upgrade as a result, along with a new warranty and a FOTUS armor code I can probably get a bit of my money back from (probably $20 or so). Your car analogy doesn't quite fit in my mind, because you're talking add-ons. I'm talking core things for the console. It's more like going in to buy the premium model of a car and saying you'll pay the base model's MSRP--you were going to get the features, whether they were free or you had to pay for them. I consider the money I was already going to spend gone, so I see what I'm getting as discounted, rather than the extras as free. OF course, the math comes out the same, so IDK why you'd bother arguing it anyway.
