All Items Ship From The USA
Shipping and Delivery
We ship from a vast distribution network strategically placed in different regions within the USA to provide fast shipping times to most locations. Sometimes your order will arrive in separate boxes if you order multiple items due to many inventory locations. Some items may ship directly from the manufacturer to you.
Most items are kept in stock, however some products are custom made to order and require manufacturing time and will likely ship directly from the manufacturer.
Expected ship dates are our best estimate based on past shipping times and are more than 90% accurate. Most products ship within 2 business days, unless otherwise noted on the product page. Should an unexpected delay occur, we will notify you by e-mail (or letter) of the new projected shipping date.
In-stock items usually ship the next business day (weekends and holidays are not considered business days).
Please allow an additional 1 to 5 business days after the shipment date for delivery.
