It probably doesn't make any difference except maybe for the cost. Square wire might cost more. As to charging for the CS, YES, it is fair to charge a price that will repay you to allow you to make more. If you give it away to the point that you cannot make more, everyone loses! I have been fortunate in that I was able to give away many bottles of CS. Now, I cannot do so. The prices that the stores charge may be honest, but, it is a lot more than it costs me to make CS.
