I have sent the wrong parcels to the wrong people by mistake whats the best/cheapest way of rectifying this?
They should return the items to you at your expense. You then repost to the correct buyers at your expense.
Under no circumstances give one buyer another person's name/address, maintain confidentiality.
I bid, I win, I pay - you deliver
Give each one a ring explaining the error,and apologise, asking them if they would kindly return the items to you, and you will immediately reimburse the postage costs on there return.
Dont get them to send on to each other as you would loose seller protection if they didnt arrive,having involved a 3rd party.
