Just to add my two cents:
As a former and hopefully recurring employee of HKSupplies, if you wish to order from HKSupplies (BTW, ebay username is "etefore" - I didn't see it mentioned scanning the past four pages). The ebay store usually has the same items listed in multiple currencies. With auctions lasting typically 5-7 days, and foreign currency exchange rates varying with greater frequency - it is a good idea to view the item listings in different currencies to ascertain which is cheapest at the time of your intended purchase. This tip has been mentioned previously by users above.
If you don't qualify for access to the bargains section on this forum, and wish to purchase from HKSupplies, you may also email directly:
sales@hksupplies.com.
Please note that English is not the first language for many of the office staff members at HKSupplies.
Ask in plain English, preferebly in list notation of what you want and the quantity, and you will likely receive a prompt reply. I suspect the majority of unanswered emails were from users who used unnecesarily complex sentences in English which are not immediately understood. If you email HKSupplies directly (as oppsed to using their ebay store), you will likely get a better price, as they do not have to add on the additional costs of ebay listing and transaction fees. This could be $5-10 on smaller cheaper items, but as much as $50 for camera bodies.
NB: everyone should understand that purchases from HKSupplies are grey market. Not only to you the end user, but to HKSupplies as well. ie. they source their products from not only Hong Kong (where they are based), but other parts of Asia, Japan, North and South America as well. In cases of warranty claims, they are sent back to their respective places when you send the item back to HKSupplies. They keep track of paperwork in a bottom drawer, and deal with any issues from the warranty supplier.... all you have to do is send it back to them (which in my opinion is less stressful than having to deal directly with a contract repairer on behalf of an Australian official importer/distributor, along with communicating with their outsourced customer service centres - which is often the case for many warranty claims on electronic consumer goods).
