I use the US Postal Service's Priority Mail for all domestic shipments, unless you specify otherwise. Priority Mail is guaranteed 2-3 business days. For international purchases of smaller items, I use the US Postal Service's 1st class mail. It is not insurable and may take a few weeks to reach you. (If you would like to upgrade to International Priority and/or insure the package, I'm happy to do the paperwork. I will send you an invoice through PayPal for the additional shipping charges.) Larger, more expensive items will automatically be sent Priority Mail with insurance, and you may incur additional customs charges. Please be in touch with me if you have any questions or concerns regarding your individual shipping situation.
