Ok dude, you win. You obviously can't read or you'd have already read the contract and TOS and found out you were flat wrong.
The "MSRP" on what you posted is there because they're preorders and the final price isn't set, yet.
The discussion was about whether a store can change the price of a product, period. They cannot. As you said, they can work with the product creator to change the price or the creator can increase the price of the product and the store cannot countermand it. Try selling something, you'll find that out. Stores only control the pricing of their own products. In the cast of Walmart, Equate. Otherwise they have a contract with whoever is using them to resell their product, just like you would contract with the App Store or Amazon, to display said product at a set price and they either get a cut of sales or charge you a monthly fee for shelf space. Walmart doesn't care about pricing of Frito Lay products as long as they get their monthly shelf fee. Sales of Fritos aren't their problem or concern. The App Store doesn't care about the pricing of your app as long as they get their cut of sales where applicable. In both cases that's a level of control they don't want or need and opens them up for liability if and when someone disagrees with the pricing.
You are clearly ignorant (or intentionally lying) about MSRPs and other things that have been discussed here. No, those were NOT estimated prices and it's absurd for you to (claim to) think they were. Those were clearly set MSRPs being announced by Sony. They exactly match the prices now found on Sony's product pages. Of course, as I have repeatedly stated, what retailers choose to sell them for can vary as those retailers (like retailers of so many different products) absolutely can have control over the pricing of products they sell.
It is unbelievable that you would actually think that MSRPs only apply to automobiles. Wow!
There's no point in continuing this discussion if you are that ignorant about the topics, or at least pretending to be for whatever reason.
