London chess books second hand

Hello chess friends (and fiends!)

I'll be visiting London for a few days next month. Could any Londoners, or anyone else for that matter, tell me of any bookshops where one can get one's hands on second hand chess books. Reasonably priced, I'm looking more for bargains than rare collector's items at £90.

Thanks in advance.

Thanks Crazychessplaya!

I'm also looking for second-hand bookstores that might have chessbooks from time to time.
