I don't use amazon (although I cheat a bit because my wife sometimes does). But for books we use indigo.ca (in Canada) which has the same selection and is importantly not Amazon. Is there another national US online bookseller?

For other stuff, I just go to the hardware store. The only real amazon thing I depend on is a kind of micro-fibre wipes I use for my glasses.

It's actually mostly happened organically since amazon got so bad, although the last few times I used it I abandoned my cart trying to navigate the dark pattern of paying without buying prime or getting tricked into shipping fees.
