Message added to cart even if product variation price is 0

Hello,

When I can't sell my product, I update its price's variation to 0.00. This product is not available in my cart, but when clicking re-order (the product was available in a past order), I have the status message saying that the product (now unavailable with a variation price at 0.00) has been added to my cart. Is there a way that I can coordinate that ?
