I know there was a thread here a while ago with someone asking for the best place to get calendars and diaries in which you add your own photos to. Photobox are running a promo until 20/10/11 - 2 for the price of 1. Enter 241CALS at the check out.
I always get mine from photobox as I find their quality and customer service to be head and shoulders above the rest. If anyone isn't already on photobox and wants to take advantage of this offer pm me and I'll send you a referral, that way we both get free stuff :).
