You can find specially priced ebooks at the B&N Nook Daily Find page. Today’s book is Living Violet, by Jamie Reed. Normally $8.99, it’s on sale for $1.99.
They also have a Nook Books Deals page for discounted books.
However, unlike Amazon and Kobo, they don’t seem to have a separate free ebooks page – or at least not one that I can find.
To find free B&N ebooks just use 00.00 in your seach.
For example: “00.00 mystery”.
