In previous years in December I would have always automatically upgraded postage to help get packages through - ie 2nd class to 1st, Tracked 48 to 24. 

Buyers appreciate this kind of gesture but with Simple Delivery it's not possible. 

Would ebay please consider offering sellers the ability to upgrade Simple Delivery postage at their own cost after an order has been placed? 

Or even better, could ebay themselves consider giving automatic free upgrades for Simple Delivery postage over the Christmas period?
