Is the seller or the buyer responsible for a lost package?
In the US, the seller owns the risk of loss until the package is delivered. That comes from the UCC's shipment-contract default and is echoed by every major marketplace policy. The buyer's remedy is a refund from the seller; the seller's remedy is a claim against the carrier.
Does adding tracking shift the risk to the buyer?
No. Tracking that shows successful delivery shifts the burden of proof under most marketplace protection programs, so the platform will not force a seller to refund a delivered order. It does not shift the underlying legal risk before delivery.
What does eBay's Money Back Guarantee do here?
eBay refunds the buyer and, if the seller shipped on time with tracking from an integrated carrier that shows delivery, eBay's Seller Protections cover the seller against that item-not-received claim. Without valid tracking, the seller absorbs the loss.
How does Etsy handle a non-delivery case?
Etsy's Purchase Protection Program, effective July 9 2026, covers up to $250 USD (including shipping and taxes) for orders that meet its requirements; the seller is not held responsible when the coverage applies. Amounts above $250 fall back to the seller. Buyers open a case 7 days after the maximum estimated delivery date and have 30 days from then to file.
Do I have to buy shipping protection?
Marketplaces do not require it, and the carriers include $100 of coverage on most parcel labels. Above that value, added declared value is the only way a claim can pay out more than $100. Without it, a lost high-value package pays only the bundled $100 from the carrier and the remainder comes out of the seller's pocket.
