SimpleCart(js) Quantity limit
<p>I'm using simpleCart(js) to integrate shopping cart into my WordPress site. </p>

<p>I am selling articles and I really don't need quantity because obviously nobody wants to purchase 2 same articles and I want to prevent users from adding more than 1 article to cart.</p>

<p>So the question is: how to prevent adding same item more than once ?</p>

<p>I just can't find a solution to this on my own, so please help me (I am OK with any method as long as it works)! </p>

<p>Thanks !</p>

<p>P.S. This is very poorly documented, but the script is very light <a href="http://simplecartjs.com/documentation.html" rel="nofollow">CLICK HERE FOR LINK</a></p>
