I like making my own Laundry Soap for more reasons than one. There are many recipes out there; http://www.thefrugalshopper.com/articles/detergent.shtml. I have created a couple of Essential Oil Blends that I use seasonally to scent the homemade cleaners.
Fall/Winter 1 oz bottle $10.00
This blend has lavender and grapefruit to help lift the spirit during those long indoor months. If you hang your clothes indoors like I do...by my beloved woodstove, the Essential Oils also help to keep the air a bit more germ free. These

Summer/Spring 1 oz Bottle $10.00
This blend has Sweet Orange, Clary Sage, and Geranium Essential Oils. During the summer, this natural fragrance keeps the clothes smelling clean and fresh. I hang my clothes outside as much as I can to get that outdoor fresh smell...this Essential Oil blend extends that very odor just a bit longer. These bottles last for about 10-15 gallons of laundry soap depending on your desired strength of fragrance.
