Oh i see, but, but, but, why do recorded as a standard option?? it gives no more protection than first class unless you use royal mail guild-lines on using recorded......ie the packet MUST be enclosed in royal mail standard bubble wrap jiffy's to qualify, you still get a receipt of postage to the address on the mailer using only first class and it gets to address no more quicker.
In my opinion P/P should be free of charge to a buyer if all they want is standard delivery, only charge if the buyer wants other than standard and then it should only cost what it has cost the seller to use other than standard.........no little extra's.
In no way am i implying you do charge any extra than the actual cost but there are plenty that do, not so much on S/S but elsewhere.
