 - when a new product with the same ID is added on a cart and a quantity is provided, it will increment its current quantity instead of overwriting it. There's a chance that you will also need to update an item's quantity but not incrementing it but reducing it, please just see the documentation (Please see Cart::update() section, and read carefully)
