Help people from london or frankfurt

[Applehead Ale]

My mum is going to Frankfurt and later London in a couple of weeks, and I want her to buy me any kind of Michael stuff, cause in my country you would find NOTHING, and if you do it's too expensive. When I mean MJ stuff I mean anything like LP's, vynil, singles, 'exclusive' CD's, etc. I hope someone would help me because I really want some stuff. Please share adresses of record stores or somewhere I can find something.
the adresses are:

London

4 Knaresborough Place, Earls Court

London, SW5 0TG



Frankfurt

Friedrich-Ebert-Anlage 40

60325 Frankfurt am Main

I beg for help LOL
