HA that your fault for not placing tracking on the package. You knew that in order to be covered by seller protection all items must be tracked online. Dont give any excuses for why you got ripped off. No one else should be out any money other than you because you cant follow directions.

This buyer was reported and eBay closed their account.

To the comment above (if it is still there):
Buyer did not upgrade to a tracking option that was available on checkout. Guess why? So they can later claim "item not received". You appear to be the same type, bashing seller and not even leaving your name here. Although eBay loves you, thieves, so much, even they got fed up and remove buyer's account . You are welcome to click on their eBay user's name above.

"Upgrade" to a service that provides tracking?

BS. Priority Mail and First Class both come with free tracking. Priority costs the same or less than parcel post. All FedEx and UPS shipping comes with tracking.

The seller is responsible for the courier, not the buyer. You are responsible for selection of the options. Tracking is to protect you. You had to deliberately search for a service that didn't provide tracking, likely so you could attempt to get away with not shipping items.
