About $150.00 give or take $25.00, summer is slower for orders. Oct.- Dec. much higher. I should mention that I have a low inventory and I tend to sell my store inventory whole about every two months. I always have a deal on it. I only get about 4 - 5 orders a month. If you have a bigger inventory, you'll get more orders. Troy probably won't tell you what he makes, the tax man might be watching.
After a long absence, I have returned. I can't wait to start building again.
