Barnes & Noble is advertising a
cookbook sale right now with 45 books listed. Prices are all over the place, but there are a good number that are $1.99 and $2.99. Most aren't B&N specific and are discounted at other sellers as well (I checked several titles at eBooks.com and Kobo).
I picked up the almost 500-page
The Easy Pressure Cooker Cookbook for $1.99 at
eBooks.com.
