These changes result in less staff available to pick, pack & ship orders which may result in some delays. Shipping carriers including UPS and USPS have announced that they are experiencing similar challenges which may result in transit delays for packages. We understand that our customers expect their orders promptly, so please be aware that while we are working as quickly as possible to ship your orders, there is the possibility of delays while your order is en-route that are entirely beyond our control. If you have any questions or concerns regarding shipping or delivery time frames, please feel free to contact us first.
