Stack is a subscription service which sends you out a different magazine each month - you never know quite what you're going to get, which means it works as a sort of taster menu, encouraging you to try out stuff you wouldn't necessarily choose for yourself. They've got a fairly varied and independent list of titles so far, including Eye Magazine, The Ride Journal, Little White Lies and IdN. (If you already subscribe to any of the titles on the list, you can let them know, and they'll send you something else in its place.) There's a service for both the UK (you can choose from six, eight or twelve magazines, sent out one per month) and the US (six magazines per year, sent out bi-monthly over the year).
Each package comes with a magazine and a couple of extras - this month the main magazine was music mag Sup. To go with that was James Bridle's 'Immanent in the Manifold City' newspaper, produced through the brilliant Newspaper Club service (which we'll be writing more about sometime soon).
Like the man says: happy reading.
