"Buyer Safety and Common FAQ's
What if an item is damaged in shipping?If an item is damaged in shipping, you should contact the seller immediately so that a Damage Claim is filed. The responsibility of pursuing a Damage Claim is solely with the seller, however, you will need to cooperate with the seller and the shipping company in any manner requested. Often, the shipping company will come back to pick it up, or inspect the package in your home.
- Keep all of the packing materials exactly as you received it.
- Do not attempt to use the item or plug it in, which may result in further damage.
- Do not attempt to disassemble or repair the item unless the seller first agrees.
- Take photos of the item and the packing materials as soon as possible.

Also I would not do item 3 on their list. I would not buy from a Seller that is trying to make me responsible for shipping damage. The Buyer has no control over how the items are packed. I received a VPI 16.5 that was destroyed in shipping due to a poor packing job. The Seller took the item back and refunded my money.
