TOS gift certificates make great gifts for your friends and relatives. A gift certificate can be used toward subscriptions, renewals, single issues, or single articles. Simply add a certificate to your cart and provide the recipient’s email address and any message you’d like to include with delivery. Upon completion of your order, we’ll email him (or her) the certificate, your note, and instructions for use. Any balance on the certificate after a purchase will remain in the recipient’s TOS account for future use.
