I ran into this question on the Anchoress’s blog last week & fianlly looked up my Amazon history:
My very first purchases:
RSV-CE (a little zipperred edition), Mass Confusion and Inside the Mind of Pope Benedict, both by Jimmy Akin.
Of course, that isn’t so much because my reading habits are exclusively spiritual (not!) but there isn’t a Catholic bookstore here I can get to.
Following purchases are an interesting mix: SF; diet/health books (for DW); history/historical fiction; religion - both Catholic & evangelical; music, classical, country (DW), classic rock & oldies (both).
So what were your first buys from Amazon?
