Free Vaska detergent sample
While you can access the form without friending Vaska, the freebies are only for Facebook fans so you might not get a free sample unless you do both steps. If the second link does not work for you, go to Vaska's Facebook page to get the link.
The freebie form asks for your name, email, and address. One sample per person per address. Give it a few weeks to arrive because apparently they are receiving a lot of requests.
According to the Vaska Facebook Info page, Herbatergent is a "liquid laundry detergent that uses real lavender and potent botanical cleaning agents to clean your clothing and linens effectively, but without harmful chemicals." The Berkeley-based company develops cleaners that use herbs and do not harm the planet.
