Shipping via USPS Media Mail. Combined Media Mail shipping is available for multiple book purchases. 

Media Mail is the cheapest option available, but the time it takes for delivery can be inconsistent. It may arrive within 1-2 weeks, or it may take between 3-5 weeks. Sometimes USPS has room to air mail it with the First Class/Priority Mail packages, so it might arrive within 1-2 weeks. Media Mail is of lower priority so if there isn't room, then it gets aggregated until there is a sufficient batch of bulk mail packages for it to be freight shipped from Hawaii to a distribution center in California. If it's freight shipped, then you may see a period of 21 days or more where you will not see any updated tracking. We assure you that this is normal and it does not mean your package is lost, but it's not likely going to meet the estimated delivery date shown on the ebay tracking details as they average it out to about 3 weeks. After the scan in California, it usually takes less than 1 week for it to be ground shipped the remaining distance and delivered.

If you're in a hurry, expedited First Class/Priority Mail shipping can be added as an option if you would like to request a quote before purchasing so that the book(s) can be measured and weighed to choose the most optimal package service.
