YMMV. I've been noticing that it's harder to find the actual thing I'm looking for when cheap knock offs are prevalent. My most recent search was for a specific brand of rat trap, but page after page of Amazon search showed products where I was unable to authenticate the product, and reviews suggested that knock offs were being sent to at least some customers. I ended up finding it easier to drive to the local Home Depot than digging through reviews trying to find the right seller to buy from.

Also a common Amazon profit maximizing trick (aka scam) is to sell a legitimate product, build up 5 star reviews then switch to a cheaper knock off and let the momentum take you as long as it can. Rinse and Repeat. Before I buy anything of consequence I sort reviews by date, and look for this pattern to save me headaches.
