how can you be so cheap and easy?

BIGWORDS finds cheaper textbooks on average than every online store in our price comparison. Because no single online store can be cheapest every time, and BIGWORDS always shows the cheapest price among all the stores we cover, BIGWORDS is cheaper on average than any single online store we cover. On a book by book basis, we look at the cheapest current price from each selected online store, whether new, used, or rental, and then compare it to the cheapest price we found for that book from all of our merchants. 35%-45% represents what we have seen, on average, over the past year. However, here are the current savings, derived from the 170 prices BIGWORDS has gathered over the last 15 minutes or so."
