title: Magento - removing products from the cart
body: <p>I need to remove cart products from a certain category (category with id = 13) when the page loads, if there is a product added to the cart from that category. I've been working on this for quite a while and researching it too, but I did not find anything that could help me to do the function to get the result I want. Thanks in advance for your help.</p>
