Well, he's talking list price, not the offering price, so supply and demand doesn't usually come into play.
List price is ALWAYS a fiction. Whether the list price is a MSRP (made-up by the manufacturer), or set by some other method, it is ALWAYS fiction.
Generally, Amazon will set a "list" price based on factors at the time that the item is first added to the Amazon catalog. So, for example, if the green version was the first version available, Amazon will set its list price based on the factors in place that day, which possibly could be the MSRP on that day.
Then, let's say, the manufacturer expands the line, adding black and blue to the colors available, and lowers the MSRP, that new MSRP will be reflected in the List price as they're added to the Amazon catalog, but the List price doesn't change for the green version that's already in the catalog. The price they offer it at may change daily, but the list price isn't going to change.
But who really cares? Why would anyone even look at the list price? List price, be it based solely on MSRP, or based on other factors in place at the time the item is added to the catalog has nothing to do with the offering price.
All that matters is what you can buy the items for today. List price NEVER means anything. MSRP never means anything. People who look at those numbers, and take them into consideration simply don't know how to shop.
I know all that. I just happened to notice the discrepancy and thought it kind of amusing since the difference in the watches is merely color. One would think with Amazon's computers doing constant analysis of prices, they would have picked up on that, fictitious or not.
I think the selling prices for all the watches varies by less than 10%.
They analyze the prices others are offering items for, and they're analyzing at what price point at their own customers are opting to buy things.
The list price is not something that needs constant updating. It's no different than the product descriptions, or other static parts of the page. There's no need to be analyzing it, let alone constantly analyzing it.
I love when newbies come charging in here and start more threads than almost anyone AND the vast majority of them are critical of Amazon. Not that there isn't anything about Amazon to criticize, but you just nitpick at things. If it's so bad, why do you hang around - just to notice more things?
Do you go hang out at B&M stores you don't like, keep walking around until you find something else that doesn't suit you and then complain to the other customers? Or do we just have a special place in your heart.
I'd venture to say it is because the dial window material type on the blue and black are Hardlex, whereas the green is mineral. Or you can believe the novella that that one guy wrote about list price something or other... :-)
