Until a buyer receives his bought and paid for product it goes through many hands from the seller to the sales department to the shipping department etc…. But I believe according to legal American law-and Jewish halacha-that UNTIL YOU RECEIVE THE PRODUCT YOU PAID FOR-the seller is %100 responsible for it. (yes that even includes a thief buyer who denies to the seller of ever receiving the product he bought and paid for and claims a thief stole it from outside his home when really he did receive it and brought it into his home) this is something that every seller takes a risk upon himself of this happening but can pay for shipping insurance with the shipping company
