You’ve probably noticed: The cover price has risen . . . As we said it would. We’re really sorry – but we simply couldn’t delay it any longer. No-one likes price increases but the way costs have risen sharply since our last cover price rise (more than two years ago!) it was inevitable. That’s the bad news. We were too late in the production cycle to increase our subscription rates to match. So if you act fast, you can take advantage. Take out a subscription to SILICON CHIP (or renew an existing sub, even if it’s not due for renewal yet) before March 31 and you will get it for the old price. You reap the benefit! YES - you will certainly $ave money by subscribing or renewing NOW - and that even includes 24 month subscriptions. Subscribe or renew now and you’ll be paying 2012 prices right up into 2015! As we said, even if your subscription doesn’t fall due yet, renew now and you can lock in the old prices. There’s never been a better time to subscribe or renew than right now. Take advantage of this once-only offer! Taking out a subscription to SILICON CHIP makes good economic sense. It is actually cheaper than buying over the counter, you are guaranteed you will never miss an issue (newsagents do sell out!) AND we pick up the postage tab. So you save both ways: you save $$$ now and you quarantine yourself against the subscription price rise guaranteed on March 31st! We make it so easy for you: Take out a subscription (or renew) via the ‘net, by email, by Paypal, by direct deposit, by phone, by fax, or even by mail! We offer subscriptions for 6, 12 or 24 months, all of which will save you money. And yes, we also arrange gift subscriptions for someone else (with a message from you if you wish).
