Customer Service


If for any reasons you are unhappy with your order you may return your purchase within 30 days of shipment for a refund or exchange. Products must be in good condition and not show signs of abusive usage. Before returning a product please read our FAQ first.

The cost of shipping an item to us is the responsibility of the customer. Exceptions to this policy are made for defective items. In that case please contact us and we will email you a return label.

In any correspondence, specify your order number. If you are returning the product please tell us the reason you are returning it so that we properly record it in order to correct future problems.


We ship the next business day by USPS priority or first class mail at a highly discounted flat fee for the continental US. For other areas, including international shipments we will adjust the shipping fee to account for the difference. We decided to cover a large part of the shipping costs ourselves to eliminate the main online shopping burden many of us have – shipping costs.


Only products shipped to Washington State are subject to sales tax.
