Why can't I buy non alcoholic wine?

I live in IL and I have been trying to find and buy a non alcoholic wine called Ariel. I am 18 years old. I had called the Legal department of the Illinois Liquor Commission and they told me I should be able to buy it since anything with less than 0.5% alcohol is not considered liquor. But the few stores I found it at tell me I can't buy it. What can I do?
