I need to order some textbooks and I need to use the 2 day shipping so they get here in time. However it would be $30 for it so it offered me a 30 day free trial of Amazon prime which would make the 2 day shipping free. However I'm wondering, if I order and use the trial and get the free 2 day shipping will it charge the $79 membership fee after I order or after the 30 day free trial is over? And can I cancel the 30 day free trial after I receive my shipment and still not get charged the $79?
I just don't want to get charged the membership fee
