If you place your order by 3:00 PM Eastern, Monday through Friday and the part is listed as "In Stock" on our website at the time of order, we will ship free from our warehouse the same day. ACTUAL DELIVERY TO YOU WILL BE DETERMINED BY YOUR DISTANCE FROM OUR WAREHOUSE AND THE TYPE OF SHIPPING YOU SPECIFIED. Orders received on the weekend will be shipped on Monday.

While we are happy to ship most items we stock to Hawaii, Alaska, and US territories outside the contiguous 48 states, there may be additional shipping fees required to get the items to you. These rates will be calculated in the checkout page prior to payment.

We are currently working with Bongo International to serve our international customers. All you need to do is place your order on this site. When you select your country, you will be directed to Bongo’s site for completion of your order and the estimate of shipping charges. 1A Auto does not have access to actual shipping, handling or other shipping fees. We do not offer free shipping on international orders. Bongo International will ship your order overseas and assist you with customer service. That’s it! Couldn’t be more simple.
