Killer Makita Deal?

Is this a great deal? It appears that the price of 4 5.0Ah batteries make this a killer deal?

I’m really tempted to buy it but want to know your thoughts.

Edit: Here’s the correct link:

For $500, you get a cordless plunge saw with two batteries and charger (no track).

With the two extra batteries and a 55" track maybe this is a good deal – if a 55’ track is what you are looking for.

At a quick glance the promotional batteries are 5Ah. What are the included batteries?

Thanks for posting this, Aaron. Looks to me like included batteries are also 5Ah according to Amazon specs.
