A: When it's on eBay. Background: I'm in the UK. I saw a m4/3 accessory that I want on eBay USA. It is exactly what I need and the price is good. The seller has very good feedback and offers shipping to "Worldwide". I'm pleased. What happened next: I tried to buy the item. I can't buy it because eBay Checkout tells me that the seller won't ship to the UK. Huh? Conundrum: Is the UK not part of "Worldwide"? Did I not just see President Obama of the USA and Prime Minister Cameron of the UK on TV emphasising the "unique and essential relationship" between our two countries? What I did next: I contacted the seller, asking why "Worldwide" did not include the UK. A terse but polite reply confirmed that the seller could not ship this item to the UK, and that the seller would not break the rule. What I did after that: I contacted the seller again, pointing out that the UK is the USA's oldest and strongest ally. After all, Obama and Cameron had just confirmed that to the world on live TV. Plus, included on the list of countries that the seller will ship to are countries that routinely stifle personal and political freedoms. The reply: We can no longer ship certain items to the UK. We used to sell to the UK but for certain items, we no longer can. The choice was not ours. So if it wasn't the seller's choice, whose choice was it? And why? It couldn't possibly be that a prominent m4/3 manufacturer of accessories wanted to deny cheaper US-priced goods to the higher-priced UK market, could it? The item I was interested in buying costs more than $100 in the USA. It sells in the UK for two and a half times the US price. After taking into account UK import duty and sales tax the item still costs slightly more than double the US price. I don't think this differential can be justified which is why I want to buy from the USA. In an era of free trade I don't see why I can't. I don't blame the seller and I appreciate the seller's honesty. I won't name the seller, the manufacturer or the specific item because I don't want to cause any problems for that seller. But I am fuming that an eBay seller is apparently being prevented by a manufacturer from selling me an item for same price my US cousins routinely pay. Has anyone had a comparable eBay experience?
