In response to the uncertainty and isolation we’re all feeling, we'd like you to know that we remain open for business and our team endeavour to keep processing your orders as quickly as possible. We believe in facing challenges together; though we usually send orders same day, orders may take an additional 3 - 4 business days to ship due to disruptions. Please factor in a few days more than normal to receive your order.
Stay safe, and we hope to hear from you soon.
