Sony VAIO Notebook Help - Is this the best way?

[emilyyau]

Hi! I think I'm going to make the following purchase this way... wanted to run this by everyone first.

I need to buy a Sony VAIO FCG-690K computer.
I live in California, most of the vendors are here but then I'd have to pay tax!

So this is what I thought I would do:

Order the notebook from Outpost.com for $3700
With an American Express Blue Card
via Ebates I get 5% off = - 185
via American Express I ask for price protection (because [Only registered and activated users can see links. Either login above or Register Now] sells it for $3399), and they give you up to $250 back per item.
+ I sign up for Blue Loot Rewards w/American Express
+ I sign up for Click Rewards and get 500 Click Rewards for the purchase.

Therefore I pay 3700-185-250 = 3265.00.
Free overnight shipping
No sales tax.

Can anything think of anything else I'm missing?
