Surely any of the little shops in the local malls will be cheaper than Elements.
Is your friend looking for a pair here because he thinks it's cheap or because he needs a pair while he's here?
I only ask because I just bought a pair of Wayfarers off Ebay for $70USD...new of course...they arrived in about a week...
The same pair on the HK Rayban site are $1300HKD...
