Admittedidly I was certainly drawn in by the question posed, "Who'll buy my lavendar?"

Curiosity is the key, "buy your Lavendar? But what do you mean?"

"Oh really? Lavendar soap? I really do like lavendar... a try for 10 cents? I could spare it couldn't I?"

With something as enticing as the question posed, you could probably rake it in on the samples alone assuming your distribution lines did cost you too much. Who doesn't want lavendar anyways?
