Pre orders and cancelling Prime

When you cancel prime trial it shouldn't effect any orders already placed. They should still deliver it free.

One thing to keep in mind with the free prime trial is that even after you cancel it, you still have it till the end of the trial month. The best thing to do is cancel straight after you sign up, in case you forget later. (And of course every month you can create a new email address and get another free month of prime...)
