If you switch the site to Australia[0] you'll notice they don't do this - it's because by consumer law they're not allowed to, and you have to quote the "drive away price"

You can't even deduct the various gov rebates or tax exemptions; only mention that you _may_ qualify.

They have a smaller and lower contrast "after cost savings" at the bottom of the page - but the price on the site is the price, as it damn well should be.
