Plenty of items in stock for most items as at 4.15pm today. Tried to get a photo of as many of them as possible. Discounts are off Harvey Norman prices (snort) but, even so, the final prices become cheaper than many AU online retailers (even more so when you add postage):
EA2700 $179.95 - 50% = $89.96
EA4500 $329.95 - 50% = $164.96
SE2800 $ 99.95 - 50% = $ 49.98
WES610N $179.95 - 40% = $107.97
RE1000 $149.95 - 40% = $ 89.97
AE3000 $119.96 - 30% = $ 83.97
AE2500 $ 99.95 - 40% = $ 59.97
AE1200 $ 69.95 - 50% = $ 34.96
Remember, http://staticice.com.au is your friend. I'm not proclaiming all of these are "bargain" fodder, but you can do the final bit of haggle work with HN ;-p
Good luck.
Did you actually buy any? Knowing HN, when you go to the checkout, they'd probably take your payment, then say "oh sorry, its actually a pricing error". :P
Edit: That being said, you're right - its % off HN prices - and if you look at staticice, you'll find most of these cheaper than HNs discounted price anyway.
