Is there any way to reduce Simple Delivery letter size from 1kg and a ridiculous auto applied postage far higher than e.g. a stamp or £1.55 under 100g large letter? Is the solution to offer free postage? Does that give the seller freedom to use RM large letter and use the correct postage cost? Any advice gratefully received. Simple Delivery seems to double postage costs for things like cards or costume jewellery and many more items that sold well.
