@sun @feld @7666 From consumer's perspective, Walmart is trying to undercut on price. But everything else about them is a significantly worse. Their product search is the worst thing ever. Not like Amazon is super great, but it certainly is the case that I have to spend significantly more time filtering through the garbage at Walmart. In the end, the only thing that I found in WalMart is 250 packs of Kraft 6x9 envelopes. The only thing! And I try every time!

One other thing, I favor heavily products sold my Amazon. If that is not available, I get those shipped by Amazon. And I take a significant price penalty, or go without, for products that are listed at Amazon, but sold and shipped by 3rd party sellers. But at Walmart, it's essentially impossible to find or favor anything sold by Walmart. It's basically eBay at this point. But unlike eBay, there's no trust system.

I don't want to go full Pauline Kael on this. My use pattern may be abnormal. Perhaps hundreds of millions of shoppers just go to Google, then order the lowest price product. In which case Walmart will drive a higher volume. But I'm not at all certain that it's the case.
