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.
