First, thanks for being awesome enough to send someone a bamboo sock subscription.  Gift subscriptions ship automatically after checkout via USPS, which usually takes 3-5 business days to arrive at the recipients address.  If you'd like the socks to arrive on a specific day, please let us know by contacting us, and we'll figure out the best way to make it happen.  We also have a fun card that you can give physically or digitally to the gift recipient that lets them know that bamboo socks are on the way!
