> Brick and mortar retailers can use radio-controlled e-ink shelf price tags for minute by minute price changes. How does that even work? You pick up the product and the price changes by the time you go pay for it? Who would like that?

In case you're not being facetious: the price would change overnight not during business hours.

Maybe not. Dropping the prices on the wrapped sandwiches after lunch hour would be useful to clear out the unsold inventory.

Sounds like a solution looking for a problem to me. For all of this complexity, Amazon rarely has a significant price advantage versus most retail stores. From a customer point of view, competitive categories have a flea market quality to them. For a company that is usually optimized for customer experience, this is a weird science experiment. IMO, they should make price adjustments less fluid. Require merchants to g…

I'm not. Parent said "minute by minute", that's why I asked. Overnight is what I was assuming too, until I read that comment. Couldn't tell if it was a joke or serious.

It's interesting to know that products on Amazon might not be the lowest price, or always close. I thought there was more manual price research and setting, like Walmart.

I've actually started switching grocery buying to walmart - because they do have the best price, and they have free shipping. With Amazon it's annoying - I have to keep items in the cart for a while to see how the price ends up. That's worth it for expensive electronics, but not groceries.

I've seen items vary wildly at walmart as well- once saw a $3 item go to $18 for a day.

Sorry for the off-topic, but why is this available free on Morning Star, and paid-for on WSJ? Don't assume Morning Star is ripping WSJ, so is the pay wall a lie (for this (sort of) article)?

the author works for wsj.. both wsj and dow jones newswires are owned by news corp. The article was published on dow jones newswires, which morningstar has subscribed to and is paying for. So the answer is, morningstar has paid for this article.. and they've decided they can make it up using ads or other sources of revenue.

Wonder how much morningstar pays to syndicate? E.G. how much advertising revenue until they break even?

That's what you'd think. But with Best Price Just For You!™ technology, you don't actually get the price on the shelf. You get the lowest listed price in the last hour. If the price is raised you Keep Your Locked In Price™. If the price is lowered you get the new better price!

You mock, but I'm sure hundreds of hours have been spending crafting that corporate grocer speak!

Off-topic: Am I the only who can never load the comments on WSJ articles? This is across browsers (Firefox/Chrome) and platforms (Windows/Mac/iOS), and even with adblockers turned off. This article says it has 36 comments, so it must be working for most, but I can't seem to figure out why it never works for me.

I try to put this on all WSJ articles that make the front page. Here is a direct link to this story that will auto-kill the paywall:

If you want a draggable bookmarklet that will bypass the paywall for all WSJ articles, go here:

It would be nice if HN would make a change to their link submission code so that it automatically changes WSJ URLs to use the Facebook redirect workaround, since they are the one major site that disabled the Google workaround. But until then we have to do it this way.

I don't see what's so special about continuously updating your price as a seller. This happens in pretty much every grocery market in the Middle East or Eastern Europe. I also don't understand how the supposedly fierce competition between sellers ends up yielding prices that are higher than offline stores. Seems the reporter missed the true story.

It's quite likely that many sellers don't actually have the stock they claim to have and relies on getting them elsewhere in case a large order comes through, which incurs an overhead. My experience in online retail is limited to electronics but this kind of inventory inflation is extremely common.

Apparently book sellers do this as well.
