I propose an unorthodox solution, offer a discount on the first purchase or offer a discount on any purchases after the first. Either way, I feel that more people would be inclined to try the product. Essentially, new customers need to be rewarded for taking a risk, most people have 0% knowledge of hypnosis and are doubtful of it, never having tried it.
If you're interested in trying it out but the price is holding you back, here's what I can do for a fellow HN user:
First, complete an order all the way to the PayPal page, but don't pay. Then e-mail me at firstname.lastname@example.org with the order ID that PayPal shows you. I will make your order and send it to you, and afterward, you can PayPal me any amount of money that you think is fair (I'll count it as market feedback).
