Well there you go, you live and learn ;-), I too learned that lesson 10 year ago. Turkey is Expensive for specs unless you are used to being ripped off in the UK.
I only have two pair here in Turkey both from UK,
I used to use Doland and Atchison yet did not get discount for having the same name, now they have sold out to Boots, still cheaper than Turkey even with designer frames,
Designer=free advertising, they should pay the person for using them as a walking sandwich board.
