Made in USANOTICEShipping is ONLY inside of US 50 states - NO US TERRITORIES IMPORTANT SHIPPING INFORMATION: Please be aware that USPS is slowing down 1st Class Shipments as of October 1, 2021 which is how our FREE Shipping packages are sent. We urge Buyer’s to Highly Consider paying for Priority 2 to 3 day shipping which is offered for an additional charge (less than what it actually cost us to ship at). All shipments go out from us to USPS by our Next Business Day as per our policy. However, for months now USPS has delayed actually checking in shipments even though they have/have had possession of them. This is of no fault to us and there isn’t anything we can do about that – that is how USPS is now operating. Delivery Dates given on Ebay are NOT put in nor controlled by us and we do not participate in the Guaranteed By Delivery Program. All shipments have tracking on them and can be tracked thru USPS (please allow up to 72 hrs after shipping for USPS to have info in their system). We are only able to get or see the same info as a buyer by tracking thru USPS. USPS 1st Class shipments can take anywhere from 3 to 20 business days to arrive or more depending on where they are going to. We have no control of how USPS operates and moves or routes mail.
