Mmm, I got it for my birthday, last july, so I don't know where was it bought. But I suppose my friends got it in a shop which is specialized in sheets, books of music, etc (I've found there the Pat Metheny songbook, a Yes "history" book,...). This is just a thought, they could have ordered it in JR's site.
BTW, tell me which city are you travelling to. I just know music shops in Valencia.
Unfortunately, I'm travelling to London today, so I won't be able to check back until next Wed. I'll try to see my friends before departure and ask where did they buy it.
Sorry I can't be more helpful.
