I think it was $599 "on sale". My local HF will honor the price from a cat or printout off the website. Then I used a 15% off coupon probably for whatever that brought it too, I probably also bought the warranty at that time but do not know if I would bother with it if I bought another today.
My opinion at this point, they are really good about just giving you a new one or your money back in the first 90 days, no hassle.
My experience is if it works fine during that time, it is going to be fine, if it is a POS, then you know the first time or two that you use it, and usually what goes wrong, I would just as soon fix myself then to take the time and effort to return it.
For instance the bolt came out of the pulley on the engine of my compactor, made a heck of a racket, but a little loctite, a new bolt etc and it has run fine. They would have fixed it under warranty, but a little time in the shop and it was good to go.
