Here's a weird thing I do to save money on Dryer Sheets. After I buy a new package, I open them up and have my son cut them all in half. I put them back in the box and use them as I need them. It has not adversely affected my laundry at all--It does not know the difference. That's it. That's how I save 50%.
Here's what other people are saying about dryer sheets and other alternatives:
