No, you don't have to be a member. But if you are a member (at a cost of $75/year) you not only get the 12 issues of the magazine, you also get a 25% discount on the cost of all of their products, plus an additional 10% during their annual "Super Sale" (going on until the end of the month), and also you get about $130 or so of free product (retail) of your choice when you renew (i.e. membership is, essentially, free).
My pleasure to post. I hope that a lot of people can become informed when I post something about health, but if only 1 person for the rest of my posting days is helped because of seeing my posts, I will feel like it would all have been worth it.
