Please contact our team to discuss if your order will be subject to these limitations. Effective March 26, 2020 and until further notice, UPS and FedEx have suspended all service guarantees for all shipments from any origin to any destination.

Due to logistical impacts associated with current events carriers are no longer offering any money back guarantees, this is beyond our control & therefore unfortunately shipping charges are not refundable under any circumstances.
