Yes, I understand that's the fee structure... but I was pointing to your comment that you don't have to buy postage through eBay. Whatever method you use to ask the buyer to pay postage, it will invoke the P&P cost being included in the listing and therefore the fees, so even if you don't use ebay's postal service thing , you still get the fee inclusive of P&P.
I don't use the ebay link to buy postage, but I purchase it via Royal Mail themselves (as I send things from other places too, and it's easier for me to have them all in the same account) - but I still get eBays fees based on P&P, even though eBay have nothing to with that element.
The only way around it is to offer free postage and pay the postage costs yourself, or ask the buyer to arrange the postage collection themselves once they've paid for the item's listing price (which would involve putting something in the description to say you're going to ask for that, and then there's all the hassle of ensuring that they arrange the collection at a time that's suitable for you - which, to me, is much more hassle than just doing it myself).
It's simply an unfair fee which eBay shouldn't be charging for, unless there is reason to suspect that something dodgy is going on with inflated postage costs.
