An incredibly significant amount of money went into the planning, research, content writing, and productions of the Advantage Series and the
Advancement Series libraries. However, once a person has the book material it is easy to copy. Thus, we cannot offer any refunds on any
purchases from this website. Even though Tall Oaks Inc bases our reputation on the quality of the books, we wish to keep our customers
happy. Should you be dissatisfied with the book quality, please send us a copy of your receipt, along with a description of the reason for your
request, and we will send you a link for a free copy of one additional book of your choice.
