Parma Vegan Parmesan is offering a FREE sample on their website. In exchange for the sample, they just ask that you write an honest review. Here is what they had to say:
If you have not tried Parma! and would like a free sample, they are happy to send you one in exchange for an honest review on Twitter, your web site, blog (send us the link), or Facebook.
Just be sure to put in the comments section that you would like a sample.
(Thanks Mojo Savings!)
