If you have your eBay account tied to your PayPal account then eBay will take the required fees automatically. However, they do not bother with amounts under one pound, but will wait until your fees go over one pound before taking them. If your items had sold, then it's most likely that the listing fees together with the 10% selling fees would have taken the owed amount to more than one pound and you might not have even noticed its inclusion in the monthly bill. Hope that helps.
