Amazon tends to (ab)use their monopoly power through things like shipping costs.
As an emporium of everything, Amazon already has a distinct advantage. Even if prices are higher on Amazon than other e-commerce sites, it makes sense for me to use Amazon because I can get 2, 3, 4 products shipped at once. That can be a big saving.
Additionally, Amazon subsidised widespread free shipping on low-ticket items for many years, in the UK they have only recently gotten rid of it[1].
That free shipping policy, while great for consumers in the short term, did starve out a lot of their competition.
And of course, the larger Amazon gets, the better shipping rates they can negotiate. My orders are now delivered to me by a "Amazon Logistics". It seems they've finally achieved full vertical integration.
