I'm signing up for Vanity Fair for TWO years - a risky proposition, as any new editor could run the mag into the ground, but still, it works out at around £1.20 per issue - but I notice they're continuing with their slightly confusing 'special issue' thing.
If the details on the subscription page are to be believed, the December issue is out on 3rd November, then 'Holiday' out on 21st November, followed by Feb on 6th Jan, Hollywood on 3rd Feb, March out on 3rd March (!) and April out on 31st March.
So that's two times when two issues wiIl appear in the same month, with March appearing IN March. Well, if it works for Vogue Italia...
