How will my items be shipped?

All items are shipped using USPS First Class Mail. Domestic packages usually take 2-5 business days and international packages usually take about 2 weeks, but can take up to 6 weeks for delivery. These times are only estimates and delivery times cannot be guaranteed.

Are there additional shipping fees when more than one item are purchased?

No, there is one flat shipping fee per order. A shipping fee is charged for the first item and any additional items added to the order will ship with no additional fee.

What about VAT or Customs charges?

A note to international buyers: import duties, taxes, charges, delays and customs seizure of goods are the buyer's responsibility. I do not mark merchandise below value or mark items as gifts. To calculate import duties, you can use this website: http://www.dutycalculator.com/new-import-duty-and-tax-calculation

Are there any countries you do not sell to?

I am unable to sell to any country where shipping insurance is unavailable or to any country where the US has current embargoes against. I reserve the right to cancel sales to additional countries if insurance availability changes or if required by US law in the future.

Are there any countries you do not sell to? (cont.)

Afghanistan, Angola, Brazil, Bolivia, Burma, Congo, Cuba, Iran, Iraq, Ivory Coast (Cote d'Ivoire), Liberia, Mexico, Nigeria, North Korea, Paraguay, Sierra Leone, Somalia, Sudan, Syria, Venezuela. Also, Russian and other Commonwealth of Independent States countries (includes Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, Russian Federation, Tajikistan, Turkmenistan, Ukraine, and Uzbekistan). Any orders from the countries listed above will be canceled and payment refunded. I reserve the right to add additional countries to this list in the future.

Insurance for Lost or Damaged Packages

If your package was received damaged, I will need to see photos of the damage. The buyer will be required to fill out any forms needed for insurance purposes before a refund will be given. For lost parcels, you must wait 20 days for domestic and 40 days for International locations. Lost claims for shipments sent to Italy require a 60 day wait before filing. Claims for damaged or missing items can be filed immediately.
