When you decide it is time to return the calculator, there is NO need to send any personal or additional information with it, the calculator has a bar-code, which is associated to your account and contains the information necessary for our system to identify it, stop the recurrent billing, and close your account. Just follow these steps.
Be sure our address reads clearly on the center of the package.

Remove the batteries (if you haven't already), insert the calculator into a plastic bubble-wrap mailer/envelope, and seal the package. Use extra tape if needed.
Take the package to your local USPS post office. This would be a United States Postal Service building. IMPORTANT: FeDex and UPS do NOT deliver to PO boxes. DO NOT ship it via FedEx or UPS.
