I generally use Amazon as a search engine to see what exists, look at reviews, then buy locally and physically if at all possible. Especially books, after they folded, spindled and mutilated too many books and their replacements.
But I'm in the same boat. A lot more often I'll find myself looking at things on Amazon's site, then seeking out the manufacturer's own site, or another retailer, to make the actual purchase.
I just don't trust Amazon anymore. So much rebranded Alibaba shit on there, or counterfeit hazards.
The latest one I got specifically stated they didn't need a positive review (presumably to get around Amazon's rules?) but it's still a bribe even if it is via an implicit debt.
