I have switched almost completely to using Google Search. It gives you results from many sites, the ads are much more clearly marked, you get a nice blend of ads, organic product results, reviews, install guides, etc and there is a dedicated shopping tab.
I also increasing find better deals from non-Amazon sites than from Amazon. And pretty much everyone gives free or very reasonably priced shipping anyways. Even USPS delivers in 2-3 business days on average for most products I order in my experience, so the Prime Next Day value is only for urgent stuff, but for that, why not drive over to your local stores and give them some business? Keeps the local economy healthy, increases competition and diversity of choices and you usually get as good or a better deal (everyone does price match these days).
In short, why use a trillion dollar middleman company with questionable ethics when you and your community is better off not using them?
