Can you cancel Amazon Prime before the trial ends? The answer is yes, you can.
Here’s how to cancel your free trial;
Sign in to your Amazon account.
"Accounts & Lists."
"Your Prime Membership."
At the bottom left under "Membership Management," click "End Trial and Benefits."
“End My Benefits."
"Continue to Cancel."
Two alert boxes on the membership page will confirm the cancellation of your Prime membership, and the date on which it will end.
If you don't cancel your free trial by the end of the trial period, you'll be automatically upgraded to a paid membership plan. You can find this date listed on the left-hand side of the “Manage Your Prime Membership” page.
