It is tricky to boycott Amazon because when I search for a product using Google, I get lots of links to Amazon, and not much else. So I look at the Amazon pages to get search terms and then type those in to other search engines, such as Bing, Brave, or Yandex, and keep going to find online shops. Since Yandex is Russian, I add my country code to my search terms. I also try adding my city name and sometimes find a bricks-and-mortar shop close enough.
