Ohh free junk! I only assume that based upon the free stuff I received when I purchased form them in the past. I have also dealt with that company before, and never again! BTW, their price is not immediate, their discount is in the form of a rebate.
Tax? Not really an issue for me, I am registered under a non profit org (have been for 3 years now), so because of this I am able to write it off. I just didn't have my paperwork with for me to get the Macbook Tax free today, so I get a $62 rebate from the government in a couple months.

So in the end, I saved a $1 over the option you brought up, got it today, and I don't have useless junk to deal with on top of it

That is the only thing that interests me from their offer!
