 USA BUYERS MUST PAY FOR INSURANCE IF ITEM is OVER $24.99.... Insurance WILL BE ADDED AND SHOWN IN THE INVOICE WE SEND.... Any item UNDER $24.99 sent AT THE BUYERS RISK  Partial cost for insured mailing is usually $1-$2.00, this gives more protection and a tracking #.  Thanks !

>>> FOREIGN BUYERS- ADVISE IF OTHER THAN STANDARD AIRMAIL WANTED... International buyers: when item won is over $49.99 we require ..and strongly urge you to request and pay for registered mailing... Approx $19.00 US . >If you choose standard AM it is entirely at your risk. Total amount due within 10 days.
