We ship primarily using the United States Postal Service (USPS) and UPS. You can choose which service (how fast) you want at checkout, but we reserve the right to change your choice if it benefits you.  Please keep in mind that print orders can take up to a week as prints are produced individually by the artist for each order, need to outgas for 24 hours, be sprayed with a UV protectant, and then allowed time to dry before packaging up. So please be aware that overnight shipping will never result in an overnight delivery. We do not estimate tariffs or customs fees. The customer pays all Tariffs.  We do not pay any tariffs, taxes, customs, or other fees for goods entering any other country outside the United States.
