You have consider everything to analise something, for example, but reality still… I am from a third world country, and $5 is kind a good money here. A new seller have to low your offer, because a buyer will not buy something from a non rating new seller, if the seller has a 5.0 rating at least. Of course, some buyer will buy something from a new seller, i am not generalizing that, but you must have a good reputation after all. So then, not always a composer is charging $5 because he is does not know the time which takes to compose something and his hard work.
