Shipping Center

Shipping - We have updated our shipping, so as to deliver your purchases in a much faster, secure and safe manner. Your order will be sent with your choice of USPS Ground Advantage, or USPS Priority Mail. With USPS Ground Advantage we can reach most domestic addresses within five days, while with USPS Priority Mail we can reach most domestic addresses in two days, and virtually all within three days. Plus, we can ship your choice of shipping within a secure package with tracking, and insurance to protect your order from damage or loss. 

We no longer ship items with USPS Media Mail, USPS First Class Mail, or USPS First Class Package.  

Domestic Orders: at checkout, you will find that we use USPS Ground Advantage, or USPS Priority Mail to ship your order to you. There are no per item charges, as all items are shipped by Flat Rate. Mix or Match items or categories. The shipping costs will be automatically calculated at checkout. Please note that all Domestic orders shipped via USPS Priority Mail should arrive in 2 to 3 days. USPS Tracking is included on all orders. If you have questions, contact us: shipping@kozersky.com  Our Shipping Rates

Free Shipping! Free domestic shipping on all orders over $100.00.

USPS Express Mail: USPS Express Mail is an option that we offer for those times when your order has to be there tomorrow. USPS overnight service is only available for domestic deliveries. If we have your paid order by our NOON, your order will in most instances be delivered by NOON or later the following day to a U.S. destination. Shipping cost is determined by weight. 

Signature Confirmation: All domestic orders over $50.00 and less than $150.00 will be shipped with USPS Signature Confirmation. This service will insure that your order reaches you safely, and securely. The cost of this service is in addition to the postage cost, and will appear as part of the shipment cost.

Registered Mail: All Domestic and International orders over $150.00 will be shipped via USPS Registered Mail. This service will insure that your order reaches you safely, and securely. The cost of this service is in addition to the postage cost, and will appear as part of the shipment cost.

International Orders: At this time, we are no longer shipping orders to Canada until the tariffs are settled. All other international shipments are also cancelled.   

International Buyers – Please Note: Import duties, taxes and charges are not included in the item price or shipping charges. These charges are the buyer's responsibility. Please check with your country's customs office to determine what these additional costs will be prior to bidding/buying. These charges are normally collected by the delivering freight (shipping) company or when you pick the item up – do not confuse them for additional shipping charges. We do not mark merchandise values below value or mark items as "gifts" - U.S. and International government regulations prohibit such behavior.

All orders shipped Insured, and with USPS Tracking. PLEASE NOTE: We use a private insurance company; U-PIC, for all insured shipments. This allows us to keep our shipping/insurance rates down and handle claims in a timely manner. Your package will not be labeled insured, but you can be certain your order has been insured to protect against loss or damage.


Want it fast? All USPS Express Mail is shipped the same or next business day after payment is received. Please note that there is a NOON cut-off for same day shipment.

Please note that all USPS Priority Mail  Shipments are normally shipped within two days.
