Why Bundle?
1) Bundling can make it easy for someone to pick up a number of CDs based on a certain interest...parenting or young adults, for example.
2) Bundling can help people listen to CDs that they may not choose based on the title but instead based on the theme. Rebuilding Christian Civilization, for example, is on the Feast of the Family. This title may not catch someone's interest whereas the theme "Family" may. This person can then enjoy an excellent CD on the family.
3) Bundling can help use titles left from previous orders without having to place an exchange. Not exchanging means more people are listening to these titles.
