UK eBay & PaypalGeneral discussions about eBay.co.uk Suspensions and Paypal.co.uk limited accounts. This forum is geared towards UK eBay & Paypal sellers.
Are you saying that they will let you go overdrawn but then charge an "unarrange overdraft" fee? If so, take out enough money so that the eBay fee transaction will fail (even having just 1p less than the amount require din your account will work), but ensure that your remaining balance is enough to cover any "returned item" fee.
Seeing as you cancelled the DD with your bank, nothing will be charged to you. On the 25th you should get an email that the echeque has failed and because you cancelled the DD, PayPal will likely remove the bank from your account.
