On my seemingly eternal karo quest - my mother will be in London in the next 2 weeks. I don't know anything about H in London, but I'd like to send her to a boutique to see if she can get her hands on a karo. I am assuming there are several stores/boutiques - where would my best shot be? I am thinking of calling the boutique and seeing if they will place a karo on hold. Is that possible? Am I dreaming? Is it best for my mother to just go in and ask? Thoughts/advice appreciated.
