Seems like everybody is saying the same thing in different ways. Just to give you our point of view.
Full resolution packages cost more upfront but are geared to giving the clients the most comprehensive coverage of their day. In the end, this type of package costs less than purchasing prints from your photographer. Most "story telling" images are not the ones you would purchase, but we feel are some of the best pictures of the day!
Best of luck to you, either way you go.
