Should be instant.
If you have not received it then if it was an ebay transaction do this >>>
Go and find the transaction in your “my ebay” > click to the right where it says sell similar > don't fill in anything just scroll down to the payments section > look in the paypal box > is the email addy in there correct with no spelling mistakes? If so then it would have been wrong on your finished auctions so come back for more advice.
