It's also worth quoting the famous business aphorism:
"Production - Sales = Scrap"
In your case, production is worth 3 times what you quoted the middleman (because the end customer was willing to pay it), what you got was scrap value, and the difference between your price and the end-customer price is the value the middleman created by selling well.
TL;DR: Learn to sell!!! :-)
