I hate my bank that I don't can buy pinksheets stocks. In Belgium they do everything so you don't buy these kind of stocks.
I also have a bankacount in Holland and there they ask Verenigde Staten € 0,50 + USD 0,004 per aandeel So If you buy wshly you pay 0.0035 + 0.004 (to buy) + 0.004 (to sell) = 0.0115.
