I live in Sydney and I've never seen a pair under a hundred darlols.I saw some last week around Circular Quay and (I'm not 100% sure, as I wasn't really looking to find the price of them, but just turned a pair over to see ..) I think they were around $ 150.Not sure who told you $ 30 but no way!!!I'll have another look this afternoon and update my answer tonight if I remember. I'd steer clear
