If you made your purchase within the last hour, you can ask the seller to cancel your order as long as they haven’t sent it yet. Here’s how: Go to Purchase history and find the order you want to cancel. Select the More actions dropdown menu and select Cancel this order. Select Submit. We’ll send your request to the seller and ask them to confirm whether they agree to the cancellation. If the seller agrees, we’ll then send a confirmation of cancellation to both your registered email address and your eBay Messages
