How do I redeem a discount or trial code?

If you have a discount or trial code, enter it in the field provided during the purchase process.
Please Note: if you register utilizing a discount or trial code that has auto-renewal, you must discontinue your subscription to avoid additional charges for subsequent auto-renewal periods. Subsequent auto-renewals will be billed at the standard price for the time-frame selected. For trial periods that do not include auto-renewal, at the end of your trial period you must select and purchase the subscription term of your choice to continue using Dorland’s Online.
