Jasmere is currently featuring Tees for Change (sustainable tees on a mission)~
you can score a $34 voucher for only $15 (and dropping).
This is a great company and the shirts they offer are not only way-cool to look at, but they also inspire! These fair-trade and sustainably produced shirts are adorned with positive messages, suggestions, and reminders.
These shirts are all made from organic cotton or a bamboo/organic cotton blend and they ofer long sleeved and short sleeved shirts. Most of the shirts are $34, but check out their "sale" tab where they have some other really great ones (including the one below) for only $20!
There is also a link on their website to sign up for their newsletter, in which they send you a code for 15% off your first order. There's no guarantee that you could use the discount with the voucher, but it is worth a try. :)
