You can choose between the following types of premium membership:

If you subscribe by PayPal, your membership will normally renew each year automatically until you cancel it, which you can do at any time: just follow the instructions you will receive in your confirmatory email. This will cancel your membership with immediate effect, so best to wait until the end of the year to do so.

Automatic renewal saves PSI and yourself work, gives PSI more security of income and ability to plan ahead, and makes sure that you won’t miss a sale or a newsletter; so please use it if you can.

But if you don’t like the idea, consider paying 5 years at a time – you’ll get a 10% discount too ! Failing that, you can still pay 1 year at a time, but at a higher rate to reflect the extra work for PSI and potential delays in your payment. To do so, please click here. This option is not available for digital membership.
