That deodorant expires? I had used up one, and went to my stash of 4 more, a girl can't smell bad- it's like an unspoken rule, and used it. It seemed to smell weird, like, the scent smelled acidic or off in some way like it had gone bad. I used it for 3 more days, still smelled the same. It was the same spring breeze fragrance I always buy. So I read the labels and learned that it had expired last year. I always buy the bonus packs too, of the buy two at a time for a better deal. I had to throw out 3 more. Yuck.
