Please only bid if you are serious about buying the item as ebay will start a non paying buyer case if payment is not received within 2 days (working or otherwise).
I usually post within 3 days but usually it is the next day after payment is received. I will post internationally but please ask for rates.
I do not accept returns as I rely on my ebay income for some of my living expenses day to day - and the cost of to and fro postage!
