The change is meaningful both as a revealed strategy, and as a new datapoint about the fear of stores becoming "Amazon showrooms". For quite a while, it's been true that even after you're at Walmart or Target, comparing multiple items you couldn't evaluate well online, it was cheaper to drive home empty-handed and buy from Amazon - which is obviously unsustainable for someone. If that ceases to be true, we might see a more natural dichotomy where stores retain an edge on "see it in person" and "want it now" items while drawing back on their competition "any one will do, whenever" goods that are more convenient via Amazon.

Looks like the price has been going sideways for 4 years with some noise up and down, and before that, come down a lot?
At Walmart, I have to interact with employees who never seem happy to be there. A good quarter have no real reason to do more than minimum. I have to wait in line most times. Now, it has been over 5 years since I've had a walmart in the same country as I am, but I remember the horribleness of 2am walmart, mostly because they would only open one or two registers, no matter line length. I also have to deal with other customers. That can be worse.
Amazon? I click a few times, possibly put in some information, and I wait for my package.
You can do the exact same thing at walmart.com - not that I advocate shopping with either company.
* There's a non-zero chunk of the population not near a Walmart or similar.
* It costs time to go there
* It costs vehicle depreciation
So if you were going to Walmart anyway, or walked there with nothing better to do you saved the money.
But if you didn't then let's say the average wage is $25/hour or so and you spent 30 minutes there and back, and fully loaded vehicle depreciation is 50 cents/mile and it's 5 miles away then you spent $17.50 to go there.
I totally realize we could argue all this back and forth but just pointing out that most of the time the "savings" aren't real if you value your time and transport. And yes, I realize most people don't value their time and treat their transport as a sunk cost even if it isn't entirely.
edit: I was assuming going to walmart in person as opposed to online, because that's what most people appear to do but I'm happy to be wrong :-)
