Based on customer feedback, we modified our shipping policy. The majority of customers would prefer a flat shipping charge and use Media Mail to save money. 

Currently the cost of first class/priority shipping is included in the price of each book and orders over $50 are discounted to reflect combined shipping.

The new policy will charge a flat $4.00 shipping and handling charge for all orders under $25. Orders over $30 will ship free. Books will be shipped using the least expensive method (First Class/Priority/Media Mail).  

Book prices have been reduced to reflect this policy. Books originally priced $10 and under have been reduced by an average of 50%.

Thanks for the feedback.
