paypal-have paid seller twice-help!

[merglemergle]

I've just paid a seller twice for one item. Not sure how this happened but I have 2 reciepts.

What do I do? If they refund me my money, do they have to pay fees?

Help!

This happened to me before on two occasions on the same day. Just send them an e-mail. They don't have to pay anything to return a payment, and if they don't return the payment, you can leave them really bad feedback, which they probably don't want to risk.

email them and ask them to return the payment. If they don't then contact PAypal and tell them what's happened and they'll refund your payment
