Due to the current COVID-19 situation, our stock is reduced and shipments may be delayed by both us and our shippers. FedEx & USPS are experiencing longer than normal delivery times.

THERE MAY BE A 1 DAY (OR LONGER) DELAY BEFORE WE CAN SHIP, REGARDLESS OF SHIPPING TYPE SELECTED!!!!

We are doing our best to get orders out, but much is beyond our control.

--------------------------------------------------------------------------------------------------------------------------------

Shipping Cut Off times: USPS 9am | Fed Ex Ground is 12 noon | Fedex Express is 2 pm

Weekend orders will not be processed until the following Monday.

We recommend FedEx as USPS is very unreliable now with priority mail taking a week or longer. We have also had several USPS packages lost and will not be responsible for any packages sent USPS.
