I received an email last night from Theology Mag that advertised Logos Basic with a free biography of Warfield by Kim RIddlebarger. I don't know which mailing list triggered it; I'm on most, if not all, of the lists. When I clicked on the link in the email, it loaded the cart with Logos Basic and the biography as separate items and entered a coupon code. The biography downloaded as a Permanent resource. So, if you get the email, don't delete it without reading it.
