I need a vacuum cleaner. I know a couple of companies, I research their vacuums. Still not sure what I want, then I see an add for foobar vacuums... Never heard of them, let me go research them too. By the way, for YOU, shopping for shoes isn't much of an issue, but that isn't true for a lot of other people. The other thing is a lot of people don't spend their time "going to an objective site"
