We ship to all lower 48 states (contiguous United States) for free. If you're interested in a product and outside the lower 48 please contact email@example.com. In some cases we may be able to get you the product you want with an additional shipping charge. Always be sure to contact firstname.lastname@example.org or 256-633-6553 when placing an order outside the lower 48.
It’s our goal to get your purchase to you as soon as possible. We provide estimated shipping times, but these are just estimations and are not guaranteed. Many things out of our control could impact the shipping time, such as supply chain issues. As soon as your order is placed, we will reach out to the supplier to ensure the product is available for immediate shipment (this does not apply to custom orders). If it is not, we will reach out to you with an arrival estimate to see if you want to proceed with the order. If not, we will cancel the order and give you a full refund immediately.
If the product is in stock (and not a custom order), it will ship within 2-5 days of your order. Tracking information will be sent within 24 hours of your product leaving the warehouse; if you do not receive the tracking information or have any questions, contact email@example.com or 256-633-6553.
All shipping information, besides the shipment price, is subject to change. With the current nature of logistics, our suppliers can only sometimes provide us with accurate information. We will be sharing any information they share with us about the shipment, but it is subject to change. For example, if a supplier tells us a kitchen package will include all products in one shipment, and when it comes time for shipment, parts of the package are shipped separately - that is out of our control. We will do our very best to provide you with up-to-date and accurate information - any information we are given, we will let you know as soon as possible.
