I don't know if the market is diminishing. It's been difficult finding a third matching Mega Tower for my collection... but it looking like I am picking one up tomorrow. The first one I bought many years ago for $100, and sold all of the cabinet's contents for hundreds of dollars... so the first case was nothing but profit for me. The second case cost me $325 and 2 hours of travel. The third case is going to cost me $600 + or - a little because of all of the travel and rental vehicle. I didn't want to ask any friends or family to borrow their large SUV to put over 500 miles on it!Thought oakley cases sold like hot cakes. Is the market on Oakley cases diminishing?
