For most lots I charge

the item price + the ‘stamp price’ + 50p*.

For combined purchases I charge

the total of the item prices + the stamp price for the total weight + 50p

For EU consignments (<£39) I also now charge (and pay)

£2.56 (3 Euros) Duty + £1 Royal Mail duty handling fee

For US consignments I also charge (and pay)

the 50p Royal Mail tariff handling fee.

For UK lots over £20 item price, I select simple delivery and ebay administers postage.

* 50p covers the cost of packaging + travel to post office
