“Amazon had 38% of online retail market share”

As a commentors above pointed out, online market share includes Airline sites, etc, and Delta alone is a top 5 online purchasing site. Show me what “Amazon had 38% of online retail market share” actually means. That they have 100% of 90 areas measured and 0% of airline ticket sales?

Being good at something does not make you a monopoly. They are not actively blocking other online retail platforms. This is not a statement to defend Amazon but the fact that I prefer Amazon for its features (like same day delivery) is just plain capitalism. The customers have a choice to buy from a retailer they prefer and the important thing is that I still have an option to choose where I make my purchases.

This exactly. I tried buying from other online retailers recently to support other businesses directly, and their websites are replete with what I would consider dark patterns. Things like listing 2-day shipping and then burying the fact that you'll get the item 2 days from when it ships but it will take them a month to process it. Seriously, this is a thing.

At least with Amazon I know I'm actually getting it in 2 days or they'll give me a refund (and often times still give me the product too).

Amazon also has dark patterns. I have accidentally signed up for Amazon Prime twice in the last year due to the way they practically force it under your cursor while you are checking out.

I do not want Amazon Prime because in my area (in southeastern Australia), it fails to meet its delivery promises about 95+% of the time, and when that happens, Amazon cancels the order on you half the time and sends it off to some distant pick-up point the other half. Regular Amazon just sends things by post, which is so much more reliable and convenient.

I strongly prefer using smaller online retailers. I have not found it very difficult to find ones that offer better and more honest service (not to mention lower prices) than Amazon. As far as I'm concerned, Amazon is for Kindle books, and occasionally the odd item I can't find anywhere else.

If you sell a thing on amazon, they require it to be no cheaper on any other site. or so I've heard.
