Every time I want to cancel a PayPal subscription I end up scratching my head, because it’s not obvious where you go. Here are the steps you need to take:
1.Login to your PayPal account.
2.Click on the Profile link. Don’t choose any of the drop-down items, just click on “Profile” and clik on "More options"
3.Go to : 
4.Click on : "My preapproved payments" and click on the subscription you want to cancel.
5.Then you will see page like this .
6.Confirm the cancellation
That’s all there is to it. Pretty simple once you know where to go. Don’t keep looking in vain for a “Subscriptions” link anywhere on the main page.
