I don't have a clue. If I was guessing, as many bows as he sells a year, I'd guess in the 775-800 range. He sells a TON of Mathews bows every year!
I just priced a Halon 5 today while picking up some 30" Rock Mods for my Chill R. There price was in black was $1050. Then add orange strings brings up to $1100.
Bills sporting goods in Claremore Oklahoma had them for 849 or 899. Either way its the cheapest I have found it between missouri and Oklahoma
Generally mark up is going to be 30-40%. Depending on he well a guy does controlling his overhead. I would bet the bows dealer cost is 6-700
