I've been using equal parts dishwasher soap (the cheap stuff from aldi), borax and baking soda. Use 2 Tbsp in your dishwasher for each load. It gets the dishes real clean. Try it, you'll save so much money.
You can also use borax to stretch out your laundry soap, it's great stuff. Not all grocery stores carry it, but Target does.
