http://www.ebay.com/itm/300969067831?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2648 Seems like a great deal, but I have a few concerns about this pair: 1. It doesn't look like the lens says "polarized" as it does on other polarized Frogs. Does Oakley still do this on the LXs? 2. There's a sticker on the lens and I've never seen that. 3. $40 below retail...how can you possibly sell a $170 pair for this price and still make money? seems sketchy to me. The seller claims 100% authenticity and the feedback is over 99% positive, but I don't want to buy if I'm not completely convinced that they're legit. Thanks in advance.
