Beware of 12 month subscriptions for Popsci on Ipad - I have recently received this email from them:
Dear GAYNOR,
We are writing with some important news about your subscription to Popular Science+.
Beginning next week, there will be a new UK edition of Popular Science for the iPad. Popular Science+ UK will include all the great news, features, photos and video that you’ve seen in the US edition, but with all the prices in pounds and measurements in metric. All the What’s New products will be available to buy in the UK, and there will be new UK-only articles.
Unfortunately, when Popular Science UK launches, the existing Popular Science app will disappear from the UK app store. The app will remain on your iPad, but future updates will not be available to you. This means that, at some point, you may lose access to new issues. We would like to apologize in advance for the inconvenience this may cause.
Since your subscription and credit card information is managed by Apple, we are unfortunately unable to transfer your subscription to the new edition. However, the publishers of Popular Science UK are arranging a special offer so you can claim the new UK edition at a huge discount.
To claim this discount, which will be available for a limited time, please visit: yeah great 40 per cent discount on a product I have already paid in full for - not thanks
