OK, I didn't see any until visiting ebay.com (instead of com.au, even though I searched worldwide, stores, etc)
Sorry about the threadjack, but this is one of my biggest grievances with ebay.
As tekdroid noticed, even selecting "worldwide" won't show you all results.
Some overseas items are hidden, for no apparent reason. After spending hours with ebay's live support, they admitted items are being hidden from searches if they don't comply to certain payment and shipping options of that particular country (courtesy of last years Paypal/bank transfer shakeup).
Fortunately, there is a workaround. Under Advanced search, select "Only show items located in Any country/region".
Logically, one would assume that this yields the same results as "Worldwide", but it doesn't!
Sample search for "Sony PCM D50" (incl. store inventory)
On ebay.com, using default basic search: 25 auctions, 16 store items = 41
On ebay.com, using Worldwide search: 25 auctions, 18 store items = 43
On ebay.com, using Any country/region:
25 auctions, 22 store items =47On ebay.com.au, using default basic search: 14 auctions, 18 store items = 32
On ebay.com.au, using Worldwide search: 14 auctions, 18 store items = 32
On ebay.com.au, using Any country/region:
25 auctions, 22 store items =47So you see, it doesn't really matter which national site you use when you search! As long as you use the "Any country/region" setting, you'll get the same results.
