Btrendie has the, oh so cute, Envirosax bags (set of 3) at only $15.99 (org $25.50). If you are new to Btrendie you will score $10 in your account just for signing up. That would make these cute bags only $5.99. Honestly, I think these would make great teacher gifts. You can head over here to check it out.
