And I counter with this (which was the link I checked before making my post - sorry I didn't do a comprehensive price search before posting):
But that is all beside the point. How long has the Wii Mario Kart been out? 6 years? (edit: my guess was spot on - it came out in April 2008) If you want to wait that long for Mario Kart 8 to be $20-$25 cheaper, go for it. In the mean time you lose out on the free (currently $60 valued) game that comes along with it. Remember this was all in response to someone who cancelled his preorder over the poster at GS and said he'd wait for it to get cheap instead.
The original post said "my wii u has sat in a drawer for months so I will wait till mk8 is cheaper and a reason to play u". My point is that it will be years, if ever, for it to get significantly cheaper. Of course in several months there will be lots of used copies available and via various coupons/sales, you can probably get it relatively cheap. Still, I think it is a mistake to pass up the free download game you get by registering MK8 before end of July.
And anyway, if you aren't going to splurge for the occasional "full price" Nintendo game for your Wii U, you might as well sell the thing as that is pretty much what it is good for. And I put that in quotes because of course there are cheaper ways to get it than by paying $60 cash: $48 via GCU + $10 gas card at BBY, $60 but via cheap credit at GS, etc. So any decent CAG is not paying $60 anyway. That's even more reason it is a waste of time to wait for it get cheaper.
I don't think it records price before 2012, but the point is that there are several places where Mario Kart Wii has been cheap for quite awhile now. Just because Gamestop (which btw is a very old page; notice how it doesn't even have a link to check local stores) or Wal-Mart won't lower the price doesn't mean jack squat to anybody who knows the first thing about shopping. FWIW I bought Mario Kart Wii for $15 (new) sometime in 2010. Even if you factor in that was a $5 off coupon, it was still on sale for $20 new, and I know for certain there was a similar sale that I missed out on before that, and a couple more after. And that was for Wii, which was flying off the shelves, not WiiU, which barely moves at all. I know sales for these titles aren't as common as many others but they do happen.... with the exception of my day 1 purchases, I haven't paid over $35 for a single Nintendo title in over 5 years (since I bought my first copy of Mario Kart Wii in fact, ROFL), and I own most of the notable titles.
I doubt very seriously that it won't drop to at least $40 at least once or twice before Xmas, if not lower than that. Unless all the fanboys are right and somehow this iteration of Mario Kart is gonna move a billion WiiU's.... which I doubt very seriously. It's Mario Kart, same as it ever was, but without the new innovation of the motion controls or the online gameplay system. It's just not that big a deal. I guess it all comes down to how much that free game code that comes with it is worth to you, and what preorder bonuses you get? I sure as hell wouldn't cancel over a shitty poster (though I would move my pre-order to Best Buy or something). But it's not unreasonable to think he can score this game cheaper later on, especially if he's not up for the hassle of selling a digital game code.
