Explain this one... If I buy something small on Ebay like an electronic part for €30 from continental Europe. They charge me €11.00 shipping. It would arrive by via DHL. Happy days. But when I go to DHL to just post a parcel of similar size. The quote would be like £30 for shipping to the Netherlands or some other continental country. Do couriers like DHL, FedEx et al charge significantly less when you have an account with them or do some companies which shop a lot of stock get volume discounts?
