I was confused in the beginning also, now I have it all figured out.  Quite often postage costs come out later (this is for labels I have printed via ebay). It would be ideal if all costs were taken out before payment is forwarded to your account, but this is not the case.  I have often had an amount for an item less fees paid to my account, and then the postage being taken from my account straight after.  What I do not like it that ebay says "net proceeds" which is the item cost, less fees but includes the postage which is owing for a label that was printed. There is an arrow at the right that shows what each amount refers to, click on that and you get all the information.
