I even look to Reddit when I am looking to buy something, because as pointed out above, Reddit often presents people with a more objective view on a product in contrast to the results you'd get simply from a generic Google query on the product.
Oh I look to reddit/HN and hobby forums when I want recommendations, but if I already know I’m going to buy something specific, like a yellow “specific brand” paint for my blood bowl team, I’ll google and look for the cheapest seller.
