I opened this box of Bounce (120 fresh-smelling sheets!) on January 5th and yesterday, on April 23rd, I washed my 120th load of laundry for the year. So while it's entirely possible that I've not accomplished much this year, it is clear that we've been quite clean while doing it.
Update: In answer to J's concern, though it's true that I have a good memory for obscure (and useless) facts, in this case I wrote down when I opened the box. I wanted to see how long it would last. And now I know.
