Purchasing Oxydol Laundry Detergent?

I have used Oxydol laundry detergent all my life. It doesn't irritate my skin or cause itching. However, I can't find it in Indianapolis, IN anymore. I purchased it online through Amazon, but it was outrageously expensive. I paid $80.00 for 2 boxes that would have cost $15.00 in the store! I haven't successfully found a substitute.
