I also have oily skin and I use Papoutsanis olive oil soap. I find that it has done wonders for my face. If you know of a Greek import market near you, you'll be able to pick up a 250g bar real cheap (I pay $1.35 for mine). I don't know if there's a huge Greek population in Indianapolis though.
Online I really haven't found anything nearly as cheap unless you're willing to buy in bulk.
No, in all these things we are more than conquerors through him who loved us. For I am sure that neither death, nor life, nor angels, nor principalities, nor things present, nor things to come, not powers, nor height, nor depth, nor anything else in creation, will be able to separate us from the love of God in Christ Jesus our Lord - Romans 8:37-39
