True. But the buyer can easily get the laptop, break it, claim it came that way, and you will be forced to return his money and accept the broken laptop. If you want to purchase postal insurance you must do so on your own dime and it's against eBay policy to charge the buyer for it. In the end you will have a broken laptop, you will be out what you paid to ship the item, and on your way to the post office to make a postal insurance claim assuming you bought it.
If there is a problem and the buyer asks eBay to review the case and eBay favors with them (which they will) you won't get your eBay fees back which are going to be around 15% of the selling price. eBay wants you to instantly refund the buyer on the first word of a problem so they won't have eBay review the case. Then you'll get your fees back.
Sellers cannot leave negative feedback for buyers. Only options are positive or don't leave feedback. Buyers can leave you negative feedback for just about any reason and there's almost nothing you can do about it.
I absolutely despise that company with a fierce bloody passion. They have no real competition because of the number of buyers that go to that site for anything and everything so they can treat their sellers however they want and they screw sellers on the word of a buyer on a secondly basis. If another company could offer me the customer base that eBay offers I'd ditch them in a nanosecond and pray to a god I don't believe in every single night that the company (and PayPal too) burns all the way to the ground.
But I digress.
