TFH has their usual once a year promo where you can get a subscription for about 90% off their standard price. You cannot renew an existing subscription, but mine always seems to be expiring as the new special comes out, so you just use the same email address to buy a new subscription. Hopefully useful to some ozbargainers :)
Not sure on expiry date, I just received the email though it does state "offer valid until April 22, 2016" (US timezone I assume)… but it just worked for me.
Terms in email:
Prices in US Dollars. Valid email address required. Offer valid for new subscription only.
New subscription order confirmed with email providing access link to MAY JUN 2016 issue. Subscription begins with JUL AUG 2016 issue. Offer code not valid under the "manage my subscription" or "Already a customer? Login here" tab. Current subscribers who order through promotion receive a separate magazine subscription. No renewal, adjustment, addition or extension to current or future subscription terms offered. TFH reserves the right not to process orders that do not meet terms of this offer.
I just subscribed after not reading this for 30 years or so. Thanks.
