That would unfortunately be way too much administrative work for us to handle. We are not the TK police and we have to assume that when you plan on putting down your cash that you are an informed customer and have your the research. Obviously, is someone is scamming then we as staff can step in, but no on day-to-day sales. It's the same as in any other situation, if you aren't asking someone who knows, they will assume that you know what you want and need.
We do sometimes try to work with sellers to give them tips on improving their product, but that is as much, or as little, my responsibility as it is yours as a customer.
