A person's "price range" is the amount that they can spend, or want to spend, for something. You usually talk about your "price range" when you're thinking of buying things like computers, clothes, cars, and so on.
When something is "out of" your price range, it means that it costs more money than you want to spend. If you want to express the opposite idea, of things that you can buy, you say:
That's within my price range.
