I'm curious how much you'd typically pay for a single hair clip? If it comes in a pack, how much would it be each?

I'm usually super cheap when it comes to DD's everyday clothes, yet somehow, I end up spending more on hair clips. My rationale is she can use it for years (at least that's what I try to tell myself .)

How much do you pay for a hair clip? Bonus, what's your favorite brand/vendor?
