Shipping - Returns - Warranties


All orders over $35, will ship for free. This applies to the lower 48 States. All orders to Alaska, Hawaii, and any United States protectorate, will be charged normal shipping rates. We use a combination of USPS and Private carrier for all orders. If your address does not accept a certain type of shipping method, please provide an additional address. An example would be if you do not accept USPS orders at your home address, we will need you to provide a good address in the event any of your order ships via the postal service.

In addition to offering free shipping, we are always looking for ways to make our shipping faster. Often times, we will ship a product USPS priority, due to it's three day shipping window. For larger orders, we ship private carrier such as UPS or Fed-Ex. Certain items cannot be shipped USPS due to their size and or weight.

Some products we sell, may be shipped directly from the manufacturer, or from a number of warehouses across the United States. If any part of your order requires shipping from a warehouse outside of our primary warehouse, or directly from the manufacturer, you will not be charged anything additional.



We will gladly take back any item that is in new/ un-used condition, and we will pay the return shipping. If at any time you need to return an item, please contact us via phone, or by E-mail, and we will send you a return shipping label. All returns will ship private carrier, and will be processed out of our Seattle Washington warehouse. Please allow up to 15 days from the time you send an item back, to the time we issue a refund. This is to allow for the return shipping, as well as for your bank to process the funds.

Typical return processing time is 24 hours, from the time we receive your shipment, till the time we issue a refund. Most returns are issued a refund, the same day they are received.
