FURTHER UPDATE
As you all know the Ebay 20% off at The Good Guys store is now live. Enter code CBIGXMAS when going through the checkout. Don't forget your 'Cash Rewards'
Prices below are with the 20% discount applied and local pick-up (add $5 for delivery)
Tab S 8.4" 16GB Wi-Fi White $287.20 - http://bit.ly/1FtfL6d
Tab S 10.5 16GB Wi-Fi White $367.20 - http://bit.ly/1xJIRbt
UPDATE As pointed out by Vermin 76, The Good Guys have the pricing on the Tab S Wi-fi models reduced on BOTH their Ebay site and their website. Their website advises the prices are current until the 1st December, so hold off on buying until you see what they do with the pricing of the Tabs as part of the 20% off Ebay sale this Sunday.
The Good Guys Ebay store have dropped the pricing on the Wi-Fi versions of the Samsung Galaxy Tab S tablets overnight. The prices are cheaper then buying a grey import from overseas and you can pick-up in store for free, but don't do that - head to Office Works and get them to beat the price by a further 5%
I've been keeping an eye on the pricing for the Tab S 10.5 16GB Wi-Fi in the lead up to the 20% off select Ebay stores this weekend (https://www.ozbargain.com.au/node/170606). It will go nicely with the Tab S 8.4 I purchased recently. The price dropped overnight from $547 to $459.
Now to decide whether or not to buy now or wait until Sunday, given there's a good chance the pricing will go up before the 20% off sale starts.
Tab S 8.4" 16GB Wi-Fi White $359 - http://bit.ly/1FtfL6d ($341.05 if you do a 'Price Beat Guarantee' at Officworks)
