Shipping▼ expand

Shipping Costs: We do not look to make money on shipping charges. We only try to cover actual postage and shipping costs. If you feel a shipping quote is too high, please contact us as we may very well be able to do better. The eBay calculator is simply one estimate. On some products we offer Free Shipping to the 48 contiguous states. For Alaska, Hawaii, US Protectorates, APO/FPO please contact us for shipping costs.

Turnaround Time: About 95% of our orders ship within one business day. If you let us know there is a rush we can almost always ship the same day. Freight items usually have a 2-day turnaround time.

Next Day Shipping: We can offer next day shipping on just about all our products even if not shown on the calculator. Please contact us. We usually get products out the same day even if paid as late as 4:00 PM MST.

Customs / Commercial Invoice: We cannot reduce an item’s value on a commercial invoice or shipping document. Misrepresenting customs values is against federal law and eBay policy.

Ship on My Account / Local Pickup: Yes, we can ship on a customer’s UPS and FedEx account. Local pickups are accepted weekdays from 10am-5pm and by appointment.

Packaging: We use only the best void fill and cushioning products. We have a foam-in-place system, full crating department, and hundreds of in-stock box sizes.

Freight / Items Near or Over 150 lbs: Many products must be shipped truck freight. We have a loading dock and get very competitive rates with all major freight couriers. Contact us if an eBay freight quote seems high — we can almost always beat it. We need a phone number and address to schedule freight. Buyers are welcome to arrange their own pickups. A palletizing/crating fee may apply for very large items.
