Unlike if you purchase by credit card, purchasing ParetoLogic via PayPal does NOT give you the option to deselect automatic renewal. So 12 months after buying you get stung for more money. On buying you get 2 emails. The important one with the registration key has a line at the bottom explaining about the automatic renewal and the receipt from SafeCart has more information, provided you read it.
Having paid by PayPal it's impossible to turn off the automatic renewal via SafeCart and no renewal email was received.
It's either a genuine mistake or a con, not sure which, won't be buying from them again.
