Things you can do:
Go on a shoe drop either in the US or in Argentina (heyo, I'm really considering doing this so if anyone wants to go in together... hint hint).
Style your Sole party (you can style a pair of TOMS shoes yourself and wear them whenever you feel like it!)

Join the TOMS team (college and high school internships).
Buy a pair!
I also just realized that Olio United, the same place that I bought my beloved rubbery Melissa shoes, carries TOMS! So does a surprising variety of shops in Portland, you can search for a place near you here.
And yes, I was referencing this youtube video in my first TOMS post.
