Amazon was price matching so they could lose money? It's not even an advertised price, you can't see the $449 number until checkout.
Huh? No, Amazon was price matching because that's pretty much what they do. Any major sale on electronics Amazon usually matches IIRC. If Wal Mart has an iPad sale, they match for example.
But yeah, the code thing kinda suggests to me Amazon's heart isn't all the way in this match. And, all the retailers make you put the xbox in your cart to see the $449 price. One of those "not allowed to publicly undercut MSRP policies".
Anyways I did a random PS4 brick and mortar online store inventory stock check for PS4 of my local area. From what I know store inventory info from at least Wal Mart and Target is not known for being 100% reliable, but we'll go with it. This is for the $399 bare SKU only, no bundles. Results:
Best Buy: in stock on website, stores within 100 mile radius or so seem about 50-50 whether they have PS4 in stock.
Target: Unavailable online, but to my surprise mostly available in area stores.
Amazon: Obviously available online.
Wal Mart: Unavailable online or in any area stores. Completely dry in stores.
Gamestop: Unavailable online but mostly available in local stores.
The overall picture seems that PS4 is becoming a lot more available, but isn't into full supply yet.
