Thanks for the replys to the other thread, but either I didn`t write the question right or I am not understanding you guys. Lets try it this way. When you buy powder say you buy 1 lb. It is $12 + $8 shipping. That 1 lb of powder just cost you $20. As you use it you are selling it to the customer. Do you sell it for the price you bought it for or do you sell it at a higher price then you bought it for?
