Free Shipping
Decor Outdoor offers free regular shipping on all orders shipped to residential or commercial addresses within the contiguous United States. Orders are delivered Monday through Friday (excluding holidays).Drop Shipping
We are an online-only luxury furniture and lighting boutique, and do not have a warehouse. Consequently, all orders are drop shipped directly from our manufacturers to your door. If your order includes items from more than one manufacturer, you will receive multiple deliveries. Because we are dependent on the on-hand inventory of our manufacturing partners, some items listed on our site may not actually be available right away. Please call us at 888.784.4644 or via our contact form with any stocking questions and we'll get in touch with the appropriate manufacturer for answers, before you place your order.Ground Shipping
Small parcel items ship regular ground via delivery services such as FedEx, UPS or DHL. Orders typically take 2-3 business days to process and in-stock items will usually be delivered 3-5 days from the date that they ship (depending on origin and destination). If there is a delay, you will be notified by email. No signature is required for standard ground shipping, so you may want to make arrangements to have packages brought inside soon after delivery, if you are unable to receive it in person.Composition and care

But before we can fully understand why the gut is so integral to our health, it’s first essential to learn more about the physiology of the gut itself—and how it works.
