It's not "taking advantage" by selling at market price. Remember, market price varies on all products in life. When I turned 16, gas was 1.50 a gallon. When I was about 18-19, I bought gas as low as .61 a gallon. Now it's friggin 3.25. Markets fluctuate, people buying set them. Personally, I have taken great advantage. I sold 500 rounds of Wolf for $300. And honestly, I could have probably gotten more. It's called capitalism in the secondary market, it's called price gouging when retailers do it.
