It has recently been announced on the SCA Announcements email list that provisions have been made to allow for the purchase of SCA memberships as gifts for those who may not feel able to renew their membership at this time, or to welcome a newcomer to our society. Instructions for this process can be found on the corporate web site: https://www.sca.org/news/gifting-an-sca-membership/
The normal membership process available on the website is not flexible enough to allow for the purchase of membership by a 3rd party, except as part of a family membership. The instructions which have been added to the corporate web site outline how to submit a request for a membership directly to the corporate office, and offer several payment options, including payment by check and payment by credit card.
As a public service, the Gazette staff would like to remind you that transmitting credit card information involves risks, which vary depending on the method used. This article provides a good overview of the safety of various methods of transmission: https://www.nerdwallet.com/article/credit-cards/sending-credit-card-information
We recommend that if you do wish to purchase a gift membership, that you take a look at the article on the risks, then review the SCA instructions for the transaction, and make an informed choice about your payment method.
