I am listing multiple books, new listings most every week. If you buy multiple listings I will combine them into 1 package if possible and give you a discounted total S&H cost. A recent example is a person who bought 5 listings who saved $15 on the total order's shipping charges. If a listing sells for $10+ I will ship them in a box. Purchasing multiple listings would almost always meet this criterion. The cost of shipping per book goes down the more I can ship in 1 package. FYI.
