To make life simpler ebay have changed their fees on buy it now sales.
Instead of a tiered charging system it is now a flat 10% across the board.
Before - if you sold something for £300 on buy it now they used to charge £8.17 + 1.5% of the final price = £12.67
From July 21st same transaction will cost you £30
Plus PayPal charges, they really have lost the plot.
