"Hundred-thousands" or "Hundreds of thousands"? [closed]

Both can be heard and used, but if you're writing them, hundred-thousands doesn't have a hyphen.

• one/two/seven hundred thousand dollars
  Shows an exact amount; often used in the context of money though can equally be used to count other things: There are a hundred thousand posts on this site.

• hundreds of thousands of balls
  Often used to convey the sense of a lot, rather than an exact number. It's a ballpark estimate of the number of things you're looking at.

In the case of your example, neither feels correct (though I'm unsure of technical correctness). I'd use something like

The company saved several hundred thousand dollars.

or

The company saved hundreds of thousands of dollars.
