Gods be good and we'll never see Walmart Web Services.

The number of times I have ordered an item and recieved texts confirming both that the item was unavailable and recently delivered is extremely high. It almost always goes "thank you for your order" "we do not have any X but will replace it with X.1" "we can't deliver your order" "your order has been delivered" with no interaction from me other than to accept replacements when I placed the order.

More competition is rarely worse, even if the competition sucks - in that case you just pretend it doesn't exist. Like I do with Azure.

Amazon gets the majority of its revenue from AWS I believe, it also always re-invests everything right back into Amazon including buying up competitors or ripping off the most popular items in their website.

Walmart interface also just sucks.

Amazon gets 1/3 of its revenue from selling things to users. This is by far the largest single revenue source.

However, it's also expensive. I believe the statistics show AWS is their biggest source of profits.

Never used walmart, different continent, but i would be surprised if there is a large webshop with a worse interface than amazons.

It is in general more awful, i will give you that, but atleast the search there is more likely to give something relevant than amazons.

Walmart is terrible, at least in my area. You order from the website, which has far less selection than Amazon, and they send a personal shopper to the nearest Walmart store to shop for your items. So it's a lot more like Instacart than Amazon.

I have never had a correct order delivered from Walmart. There are always missing or wrong items.

There’s different kinds of Walmart ecommerce shopping. Marketplace is from a third party seller. Often the same sellers as selling on Amazon. It may even ship from an Amazon warehouse.

I distinctly remember being literally unable to complete a purchase through Walmart's mobile site or phone app the one time I had the misfortune of trying. Must be internally dominated by brick-and-mortar people or something because it really is crazy how bad their digital presence is.

Aldi on global scale is bigger than WalMart.
