Interesting!
I never use a whole sheet, and that cuts down on the scent (bothers my asthma). I've found that 1/3 of a sheet will soften and un-static a regular load of laundry. "Your mileage may vary" but see if you can get by on a smaller piece of a dryer sheet.
I've also found that the store-brand dryer sheets are less heavily scented than the name brand kinds. Cheaper too!
