Definitely. I worked for a couple of years on a startup that aimed to help people make better shopping decisions. In user interviews and tests, we really saw the pain. The technical term for this is "tyranny of choice". [1]
One important distinction here is that shopping behavior tends to fall into one of two modes, optimizer and satisficer. [2] Satisficers just want to pick something adequate; optimizers want to pick the best thing. Everybody does both, but people tend toward one side or another.
People here surely skew toward optimizer, so the problem is especially painful for us. Amazon's reviews have become so reliable that my first stop will often be something like Consumer Reports, Wirecutter, or SweetHome. Knowing that some other optimizer has already done the research lets makes me more comfortable making a satisficer-style choice.
