Oversize and Heavy Item Shipping Fee

The item you are purchasing is either packaged in a very large box or is very heavy. These items tend to require special shipping and handling.

Here's how it works:

Order the new part from our website and pay for this shipping fee.

For large items such as washer tubs, and baskets, we may use a freight company to deliver the item to you. We will contact you with more information on such orders especially to schedule a delivery with the freight company. Very rarely do we ship these items with UPS or Fedex because they have size limitations on what the drivers can carry. Please pay close attention to your tracking # provided at the time of shipping.

For HEAVY items such as compressors and motors, we may use a freight company to deliver the item to you. We will contact you with more information on such orders especially to schedule a delivery with the freight company. Very rarely do we ship these items with UPS or Fedex because they have weight limitations on what the drivers can carry. Please pay close attention to your tracking # provided at the time of shipping.
