I have the tan hobo in medium and I LOVE IT! It is absolutely worth the money, and a fabulous day bag. I get so many compliments on it all the time, and it fits so much stuff in it. Plus, many of the websites it's sold on have 15-20% discounts running constantly.
I got mine from activeendeavors.com, but I'm afraid that they no longer stock all the colors. Try reesycakes.com for discount codes, there are tons. I think that fengjunk store heavensent posted above has a 15% off code circulating. I know that nessaleestyle.com and some other websites also stock the bags, but be warned that most websites don't accept discount codes on preorders (when I got mine all that nessaleestyle had were preorders).
