That is utter nonsense. It was not in a big EU or US city. It was in a shop close to a city of about 100,000 inhabitants in a non-EU country of 8 million inhabitants (not the biggest country in the world), granted the VAT is lower than the EU at 8%. If they can RETAIL machines at that price, there is nothing to stop individuals from buying them from the retailer, shipping them to Cyprus, even paying the VAT again at 15%, and selling them for much less than the regular retail price.
Economy of scale doesn't play a big role. Importers buy direct from the manufacturers who may (not always) offer 5% extra for buying by the thousand, as opposed to the hundred. VAT is +/- the same everywhere. Transport and import charges are pretty much the same, irrespective of the size of the lot, but as these represent a small percentage of costly items, such as electronics, it is not really significant (less than £1/kg by surface). A fax machine weighs what? 4 kg, so that it would cost, at the most, £4 each to import them into Cyprus by the hundred, while it may be £3 each to do the same by the thousand into Germany, France and the UK.
No, your arguments are too thin. The public on this island are being taken for milch cows.
