I'm using WooCommerce for my site and I want to ask for your help.
I have one product in my store and I want this product:
1) If customer did not get another product(s) from my store, they can't purchase this product (locked but shown in Store listings).
2) Automatically assign 'Free Shipping' if the customer buy another product(s) in my store (I'm using flat rate shipping method as my default shipping option for another products).
Any idea how to do this?
