Polishing the Pulpit Audio

I just discovered yesterday that the PTP audio is available in sets smaller than the set of everything.
Here's the link if you would like to look at it:

You can also search by title (if you know the title of one you are looking for) or by speaker - and it goes back several years.
I hope this is helpful to you.
I have had some questions about the Brad Harrub Contraceptives session that we attended. Here's the link to the set of ten that includes that session: http://www.housetohouse.com/store/Product.aspx?pid=452
