The new denominational base packages have a lot of good stuff in them. Often times you can get books you want for less by purchasing a base package. For example even though I am Reformed I purchased the Anglican Bronze, Chaplin, and Lutheran Gold. In each case I paid less for books I wanted than if I would have purchased them separately. Granted I now have items in my library I will never look at, such as Luther's German Bible, but I always have the option to hide them.
Some Examples:
The Anglican collections have the ICC and lots of NT Wrights works.
The Lutheran has the Continental Commentaries and Bonhoeffer.
The Chaplin has some of the Lexham Pastorum series and some good counseling resources.
