I don't understand why if it's a regulatory operating fee why it doesn't affect both sellers and buyers? After all as a seller we take time to list, picture, pack, drive to post office etc. yet for the buyers it's free, nada, gratis to use the site. As a buyer you have the expense if shopping in a high street of the cost of driving there your parking any bags you may need to purchase etc. so passing a few pence cost to buyers instead of fully loading it on to the seller would seem a much fairer approach.
