In-House Shipping

We offer in-house shipping for our auctions. As a buyer, this simplifies your buying process – one stop shop! There is no need to spend your time hunting down an outside shipper. For our consignors this is an important service as it will maximize the bidding potential as our shipping is offered at our cost, not as a profit center.

Estate Sales

Do you have a full estate? We can help you determine if any items are better sold via an on-line auction environment and then help refer the best on-site estate sales company. We always recommend not to throw anything away until your estate has been looked at. Many items have value that may not seem to!

For potential estate sale services call us at 509-725-5600 for a no-obligation appointment.

Appraisal Services

If you are in need of an estate appraisal, we can refer you to a top appraiser.
