Sorry if this question has been asked before... I stopped by the local Oakley Store yesterday and I noticed that they still have some Juliets - mostly the "old standbys", like Plasma/Fire, X-Metal/Black and Carbon/Black. I'm wondering if it would be worth it to grab a pair while I still can. Maybe as an investment, maybe not as I will want to use them. In any case, I'm worried about the future availability of parts as it seems that Oakley stops supporting discontinued glasses relatively quickly. Any reason to grab one or two at full retail?
