It seems if a UK buyer it shows the same as the hammer price/BIN price of the item, overseas it seems to incorporate the postage charges. Once you have sent payment details the buyer will get that total to pay, eg with postage.
I had noticed it a few weeks ago, but the totals customers are paying is correct. If you have flagged it then there is probably not much else to do, it will get sorted.
