I used to be all-in on Amazon shopping, that's where I started all my shopping searches.
Now Amazon is my site of last resort for everything but books. The rest of the net has gotten competitive. I do my research on wirecutter/reddit, and buy it from manufacturer/walmart/bestbuy, other niche trustworthy stores.
The cash back I get back from my Amazon card usually covers cost of most of what I still buy from Amazon, so Amazon has become my "free goodies" shop.
I think this is great. Having "an everything store" that everyone uses always felt like a monopoly ripe for customer abuse.
