Comment: The magazine economy is very different (Score 1) 562
There's a middle-class tradition of subscribing to Private Eye, partly because in the 70s and 80s it was slightly harder to get over the counter due to WH Smith's refusal to handle distribution, and partly because they make it insanely cheap to do so because they need the cashflow. If you want The New Yorker or US Wired or something, again you get a subscription because, even airmail, it's half the price of buying it over the counter (I subscribed to US Wired from 1.2 until it became a life-style magazine, and I've subscribed to The New Yorker for fifteen years or more), and the same applies to things like Time. But for UK-published general interest magazines, it's usually bought at a newsagent or delivered by a newsagent. "Trade" publications, for which a lot of the readership will either get it free or have it paid for by their employer, are done by post, but that's a rather different market.
So that's why there's no subscription cards (or very few). They'll sell you a subscription if you want, but it'll normally cost you twelve times the cover price. They might throw in a small discount or a gift, and you're probably getting the postage for free, but it's lot like US publications where even an international airmail subscription is about half the cover price. You might opt for a subscription if you live in the sticks where there's no handy newsagent, or as a way of giving a gift at Christmas, or if the magazine you want doesn't have proper distribution. But in general, you don't. That we have as a household three magazines on subscription, and have had as many as six, is extremely unusual in urban England.
