Based off of the link below and the price I can see, the 127 volume Fathers of the Church series is 60% off, which appears to bring the price down to just around $900.

I remember paying $1700 for this series when it was the pre-pub price, so for anyone who was wise enough to wait, now maybe be your chance to pick this up.
Also, maybe its old policy now, but I remember Logos once promising that the Pre-pub price would be the lowest price it ever offers on a product. Seeing the $800 price difference here puts a bad taste in my mouth.
