farex: The A380 is legitimately being sold in Sony Style outlets (KLCC, Times Square, The Curve).
Sony Style = owned by Sony
Sony Center = owned by dealer
Then, there are dealers (Tarita, Bintang Maju, Boeing) who carry original Sony stock.
Finally, there are third-party dealers who buy stock from local dealers, but do not talk to Sony directly (smaller shops e.g. Leos Trading, YL Camera).
Ultimately, the shops that have the A500 can order it through Sony. They just need to order a lot. You can verify that it is local, by looking on the box - there should be a white label with black bold text somewhere on the box, which identifies which dealer Sony originally sold the stock to. If you see some dealer you've never seen in Malaysia, and there's no Malaysian warranty card, then you have reason to believe it could be from a non-Malaysian dealer.
It is a very common thing for shops to claim another shop is selling fakes. "Huh how come so cheap? Sure underwater set!" Actually they can sell for cheap because they sell a lot of units and get 'kickbacks'. You sell XX amount of units, you get a free flash or other accessories.
Only way to find out is to go to the shop and inspect the goods!
thanks for the explanation, yes I know about the a380... i was talking about the a500. i been looking at this model from sony before i bought my a550...
