    Scientific American Subscription 20% off

    I guess the price for which we subscribed includes the offer ;). Its cheaper than sci.am. in my country too. Thanx to euro/$ ratio, it turns out only 1.83eu per magazine. And if you imagine that one can buy each (american edition) magazine for about 3-5eu its a really nice offer. Thanks.
