News flash, chai!
I finally tracked some down!
This was in the suburb next door to mine. The woman in the chemist shop was actually in the process of
ordering some for me, would you believe, because (not at all surprisingly) there was none on the shelves. Then she suggested I try the supermarket opposite, first. And eureka! There it was on the bottom shelf of men's hair products. It was like finding gold!
So, I will report back later.
This'd better be worth the effort!
