Oh I see, I suppose I'm getting it in English because I'm registered on ebay.com, so even after searching for hk items, it shows in the Queen's English for me.
This happens if I stumble onto say, ebay.co.uk and click on My eBay from there, all prices will be shown in GBP, I assume perhaps because that's where the software thinks I am starting from.
Now that I think about it, how about if you try the same as before to search, but start from ebay.com, any difference?
