“It's a little out of my price range.”
You're shopping for a new laptop computer at a store. The salesperson suggests getting a computer that's really nice but costs a lot of money. You don't want to spend that much money, so you say this.
It's a little out of my price range.
When you describe something as "a little ___", it actually means "a little too much". For example, if a woman is trying to decide whether to go out with an old man, she can say:
He's a little old.
This means "He's a little too old for me to date."
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.
