This is a great topic! I will explain my understanding.
Example:
Buyer sends payment to the seller for a preowned Velodyne HGS-18 subwoofer.
SELLER has both the sub AND money! ACCORDING TO INSURANCE COMPANIES (AllState, Farmers, etc.) if the unit is stolen from the SELLER at this point, the unit 'does not belong to the SELLER' but the BUYER. At this point, the BUYER is not responsible for an action that they had no control over and must rely on the seller to refund the money. Usually, an acceptable deal, UNLESS the insurance company takes awhile to pay the claim the the SELLER has no cash to pay the BUYER back before hand! NOW, with that said, one would believe that the BUYER is now the legal owner, BUT, this is NOT how UPS, FEDEX, etc. views the situation.
To the shipping companies, the product belongs to the seller UNTIL delivered! This is why as a buyer you should INSIST on insurance, and COD payment option! At this point, NO RESPONSIBILITY is on the BUYER until he/she takes delivery!
This is a FACT, anyone that works in the insurance industry, feel free to correct/comment.
