Sorry, not being cheeky, but: https://www.google.com/search?q=alternatives+to+amazon

I don't need a lot of things, and I just buy local, or for tech, sometimes Newegg, or again, a local outfit. Hit up Costco once a month, too.

At first it was a conscious choice not to use Amazon, but later it just kind of doesn't matter anymore. If they didn't exist, it wouldn't matter to me.
