this does not seem to be worthwhile for someone wanting to purchase something, my estimates as to if something is worth counterfeiting requires me to have a rather deep understanding of the brand's importance in the world that I would not have for any but the most notable brands, aside from that I have to know something about how easy/costly it is to counterfeit and get things on Amazon to make a model in my mind if the brand was important enough for someone to fake it.

So, for example, if it becomes significantly cheaper to counterfeit things the importance of brands counterfeited (in consumer reach etc.) should drop.

That's a lot of variables. Think I'll just go to the store.
