My distrust of Amazon started when I had a baby. It felt like about 80% of the stuff I ordered at first was junk. Maybe not fake, I don't know, maybe I was just being too trusting with what I was ordering, but either way it was total junk. So I started reading reviews a lot more carefully. This didn't help, I still just got junk. So then I started only ordering things from brand names I recognized. A couple times I messed up and didn't order from the actual manufacturer, and got fake or refurbished items. Then I realized if I'm just buying brands I recognize, I can just as easily pick them up at Target for the same price. My Amazon purchasing has dropped way down since this experience.

Edit to add: just last week I ordered a potty training seat from Amazon. Great reviews. Supposedly installs into every kind of toilet. It shows up and, predictably, does not work properly with any of our toilets. I wish I would have gotten it from Target or the local consignment store where I could look at it and ask about how it works, and I probably would have if not for the lock-down. So Amazon is getting my business right now, but it's very begrudgingly.
