The Bargain Hunter: Roll-On Perfume Under $20

Kate walked into the office today smelling pretty great. I’ve never been a scent lover (even my laundry detergent is scent-free) but now I want to give perfume a quick whirl. The most non-committal way is with these cheapie roll-on perfumes. They’re under $20.00, and if I don’t love it, I won’t be devastated. Any recommendations? I like scents that are fresh and clean!
