How can I have Google Checkout charge a subscription every 2, 3 or more years (longer-than-yearly)? Can PayPal do this?

Is it possible (and, if so, ho开发者_开发知识库w) can I have Google Checkout charge someone for a magazine subscription every 2 years (or 3 years or 5 years). The idea is someone pays for a 3 year subscription in 2010 and then is billed again for the next 3 years in 2013.

How can this be done?

If Google cannot do it, can PayPal?

Thanks!

For Google Checkout the max period for recuring subscriptions is one year.
