Brandon and Mitch, they're not that much. I'm making maybe $5 of profit, and all of that is going into more bolts, tubing, shipping tubes cutting wheels for my Dremel and angle grinder, and drill bits. Like Ryan said, make it yourself.
haha if your paying 40 dollars your getting ripped off to the max, I bought my square box section for around 5 british pounds and thats with bolt, so $10 for you.
