Amazon again offers Abrha Molla Wagaye's Chemistry: Principles and Applications Kindle eBook (pictured) for free. That's $60 off and tied with last month's mention as the lowest price we could find for this 855 page teaching guide.
Also available is Paul Carson's Number, Algebra & Trigonometry - In 24 Minutes: Books 1 - 24 of the In A Minute Series Kindle eBook for free. That's a $28 drop from list and another low.
