I have $6.10 left in my promotional credit any books in this sale actually discounted enough to get?

I found the ones in my wishlist but everything else I'm seeing I'm still paying 5-10$ after the discount is applied.

I love Brandon sanderson books just finished the hunger games books, read Piranesi earlier this year and loved that and enjoyed project hail Mary and the Martian to give an idea of what I enjoy reading.
