I put my laptop in on eBay to see if it could be sold. Now the auction was over and there was a buyer. He had already paid, but I changed my mind. I'd rather keep it. Is there a way to undo everything?
No, sold is sold. You could offer them a replacement device that is equivalent.
That's what happens when you want to play with the adults.
Sold and paid for? The buyer will speak to their lawyer and you will be sure that you will never want to see this laptop again.
No! An ebay auction is binding for both partners. The buyer can even sue you for delivery of the laptop or claim damages if he has to buy it at a higher price elsewhere.
"Just to look" is the wrong place on eBay…
Is there a way to undo everything
ask the buyer to cancel the purchase; whether he does that…
Now the auction was over and there was a buyer
Congratulations - and where did you start it… 1 euro
so you can send the laptop for the amount, first money then goods. Oh, you didn't specify any shipping costs! Then it is free for the buyer. YOU pay for shipping.
to see if it can be sold.
Ebay is NOT a playground
