That's not how much it actually costs. Read the entire terms, that is a placeholder open loan for $1200. You don't pay anything until end of the first month and it will be adjusted accordingly. It pre-approved the loan amount for $1200 to expedite the process, how do you think you got approved so quickly?
I kinda figured (it did say this was the maximum amount) but I've never taken a loan for anything before and I sure wasn't going to sign for it without knowing for sure I was going to only pay the $720.
It's a moot point anyway, I ended up finding a Series S on the Source's website. Never actually thought to look there and no tracker site said they were available there, so lucky me.
Finally I can use my shiny new nextgen console for what it was built for: Playing Banjo-Kazooie on a 4K TV.
