More often than not I'm trying to buy things not on Amazon anymore. Like my most recent (and expense) purchase was a telescope from Orion. I just don't trust Amazon to vet their sellers. If they can't be bothered to make sure what's sold is the real thing then I'm not going to buy from them. It might cost me a bit more in the retail price but at least when I buy from decent online stores or reputable bricks and mortars I know I'm getting what I expected to buy (even if it's not top of the line).
