I am wondering if there is any way to check in cart if a products has multiple variants already added in cart (not if the products added cart have multiple variants to choose from, but only if a product that has multiple variants, has more then one added in cart). Doesnt matter how many products are added in cart, if atleast one is added with 2 different sizes, i need to show a message. Thanks!
Maybe a way to check if any of the handles of the products in cart appear twice? I think that will achieve a similar result.
