The choice of carriers depends on a variety of factors. Most in stock items will be shipped via UPS, FedEx, DHL or USPS as per your selection. Please note that if the product listing shows "ships from manufacturer" then your shipping selection may be changed. Certain manufacturers only offer delivery via a specific carrier like FED Ex, UPS, DHL, USPS and etc. If you have an URGENT order please contact us to be sure it is available to ship immediately. Urgent orders shipping domestically should select FedEx 2Day or Next Day service, Priority Mail is NOT a guaranteed express delivery service. FedEx only runs Monday through Friday so if ordering on a Thursday and you select FedEx 2Day, that means it will be delivered on Monday. Next day air on a Friday order is Monday delivery and so forth.
We do our best to ensure that the shipping estimates are accurate. While our automated system does a good job on domestic orders within the 48 states, customers in Hawaii, Alaska, and from around the world can sometimes experience errors in shipping estimates. We will try to ship via your selected method however if the shipping estimate is incorrect we will contact you. If you feel that your estimate is incorrect, please e-mail us. Include a list of parts and full shipping address so we can provide the most accurate quote. International customers are responsible for all import fee's including taxes and broker fee's. This is out of our control and not calculated in our shipping quotes.
