If you are charged for shipping on multiple chairs, American Dental Refurbishment will reimburse you for the additional shipping charges as with multiple chair package orders we offer free shipping. All shipping on other products not weighing over 100lbs will ship UPS or an equivalent service provider. Any Package over 100 lbs will be shipped freight. For all chair packages and packages being delivered and installed or packages shipping standard freight you must allow 6-8 weeks for delivery. Office Packages must allow 10-12 weeks for delivery. As we are currently adjusting our shipping rates we ask that if there is any question about a shipping quote then you may call us in advance. We would love to assist you!
