On WooCommerce single product pages I use flat rate shipping on products that people can customise online.
I use gravity forms so customers can fill in what changes they want - add a name etc… On the bottom of that gravity form I’ve added a checkbox if the customer wants to add a Gift Box.
But adding a gift Box changes the size and shipping Rate for the product.
Is there a way that I can in the background add extra for the shipping - or change the shipping class when someone adds a Gift box?
I could probably work it out with variations or using weights - but I have 100 or more products and I hate to change the shipping calculations if I dont have to.
Thanks in Advance.
