Hello, im searching for old issues of some thai magazines ("Looker Magfrazine" from this year,2014)

There is a shop in Siam who had some backissues of magazines, i went yesterday and, not anymore.

Somebody know if there its a kind of, newsstand or bookshop where i can find it?

Also interested, do you know if any place sell old magazines ? Maybe at Chatuchak or is there any shop somewhere in BKK ?

Thanksssss.
