The term reseller is directed to trading, which is the action a trader does, and i cn tell you that a trader is just like anything else in the world
Otherwise, grow your own vegetables instead of buying from grossery stores, and trust me, those are the true "scammers"...
Have you ever wondered why they make such nice promotions when they dont sell so much of a product? :P
anyways, a trader is like youre grossery store, and since you buy from them, that makes you the costumer, which means that you decide the price of the market... if you decide, "i dont want this, its overpriced" then theyre gonna lower the price after a while, of course, it cant just be you :p, has to be a big sample of costumers so that it impacts the sales on the product...
