I combine shipping charges. It is $4.95 for the first Book/Magazine than $1.50 for each additional.  Heavier books may be more for shipping.  I ship via USPS media mail.  If you are using the BUY IT NOW feature and plan on purchasing multiple items of mine, you must add all of my listings you want to buy to your shopping cart first. The shipping discount will then be applied.  Once an item is paid for, it is subject to being shipped.  Box J-1
