Made in Oregon, USA

We ship most of our packages Priority USPS with tracking. For orders with a shipping weight under a pound, we offer 1st Class Package shipping with tracking.

We send out packages M-F, except for federal holidays when USPS doesn't ship. If we receive your order before noon (Pacific time) M-F, it will likely go out that day.

We are now shipping to Canada! This is new for us and we're refining our automated system as we go. We will refund any excess shipping charges.

Packaging materials - With some exceptions, we only purchase paper packing materials. They're a renewable and recyclable resource and we like that. But we do reuse plastic/foam packaging material that we ourselves receive in our own orders.

If an item is damaged or has been sent in error, we will replace it and pay for return shipping if item is returned within 30 days of time of purchase. If you ordered the wrong item or changed your mind, you can return it within 30 days of time of purchase and be refunded the purchase price minus a 10% restocking fee.
