Amazon has a goodly number of HarperOne titles marked down to 99 cents, and a much larger number down to $1.99.

HarperOne is the division of HarperCollins Publishers that does most, if not all, of the religious publishing for HarperCollins. However, some of HarperOne's books have only the slightest connection to religion--like ones on personal success and self-development.

While there is a wide spectrum of religious subjects represented, relatively few can be considered of "Christian Interest," specifically, although Christians will find a substantial number of titles that might make good reference material.

These books are, almost certainly, all "backlist" books. I've seen many of them marked down on Amazon before, some quite a few years ago.

I'll let you explore for yourself now. The following web address should give you the hits from a search of the marked-down HarperOne titles, filtered by price, low to high.
