Today I bought an Asus Transformer 32Gb with Keyboard dock for $649.99 from Costco Auburn.
The 16Gb version is advertised as $50 off until the 14th of August (which means that it would sell for $445). I couldn't get the story straight from Costco staff in relation to the price of the 32Gb Asus Tablet. I asked a staff member about it and he told me it was $699 and the $50 discount would not apply. However once at the register I found that the price was actually $649.99. The discount was not applied to it, but I was happy anyway as I didn't want to purchase the dock separately.
Thats a good deal you got there, with the AUD the way it is now, this makes it pretty much Amazon pricing that you got (plus Amazon don't ship the kbd dock anyway).
