Google is unusable for product search. It's too heavily gamed and optimized not to show you things you want to buy, but things Google is paid to show you. It makes it too difficult to get the information you want to make the purchases you want. Try shopping for a car or hotel room sometime on Google. None of the information is reliable, and none if it is for what you want to see or ordered in a reasonable way to navigate. They're paying too much money to try and get your eyeballs at this point, and I wound up not making purchases because of it.
