This elegant and versatile knit poncho is just $21: 'The perfect travel shawl'

Remember all of those flowy dresses, fun short pants and breezy tops we wore over the summer? Well, we have now entered early fall. Big sweaters are too hot, but a regular top is often not enough, especially in the evenings. But there's something to throw into the mix that you might not have seen for a while: the über-flattering and versatile knit poncho. If you're itching for something different, Amazon is offering up the Puli Poncho Sweater for just $21 when you apply the on-page coupon.

Why is it a good deal?
