Hate to be the bearer of bad news, but the price of RT armor has been steadily going up over the last 18 months. I personally think it's supply and demand. He has a several month waiting list, why not raise prices and see what the market will bare, if it holds raise them again.
I'm not knocking the RT armor, I was planning on getting it. But when I got the cash and RT send me the current prices, they were once again just out of reach.
