Why does SL sell paperbacks?

We DO buy paperbacks whenever possible because:

  1. the lower price for our customers, who are often on tight budgets
  2. reduced weight for shipping.

For our overseas customers, who we try to serve in every way possible, the added weight of hardbound books would be expensive for shipping costs and/or very heavy to carry if they or a courier were to deliver the books.

While we occasionally get a request for hardbound books, the vast majority of our customers are happy to have the content in the most cost effective and easy to store format--paperbound.
