I was glancing at the home page when loading Logos today and saw a blurb from the Blog about the April sale. One collection in particular grabbed my attention - the Theology and Doctrine Collection. I got it back when it was on prepub almost a decade ago, personally, and have been quite glad to have it.
Highlights for me include Juengel's monograph on Justification, Hegel's on early Christology, Webster's book on Barth, and Porter's on the Resurrection. Also good are the volumes by Gunton and the intro to Aquinas - and anything by Stanley Hauerwas on medical ethics is almost self-recommending.
There is quite a bit of great research in this collection - check it out. I strongly suspect it will be worth well more than the monthly sale price for you.
