Update on UPS Shipping During Coronavirus. Click Here
Update on USPS Transit time - USPS has extended their transit estimated on Priority Mail up to 5 business days currently.
We are seeing an unprecedented number of mis-routings with the Post Office and "operating conditions" delays with UPS. Please understand that these delays are out of our control and there is no refund on shipping services due to UPS removing that option in Late Spring '20.
