Since coming to HK I've struggled to find things for prices that I think are reasonable.
I live in Causeway Bay, and everywhere here just sees to have expensive versions of everything rather than cheaper stuff.
I was after a cheap 3.5mm audio lead yesterday, which back in the U.K I would have probably picked up off amazon for no more than one or two quid. Could only find one shop selling some premium version for 90 dollars. Had the same issue when trying to get a HDMI lead before. I'm probably looking in the wrong place..
