Yes, it does.
Our products will display availability if we have inventory in one of our distribution centers.
If we do not have inventory on the item(s) you are looking to purchase, but we have a reasonable delay until they are back in stock, then you will be able to add the item(s) to your cart and the order will ship when it is ready.
If we do not have inventory on the item(s) you are looking to purchase and the date for replenishment is too far out, the Add to cart button will be temporarily disabled until we replenish stock. If you do not wish to wait for the items to come back in stock, please reference our Where to buy page or view the find it locally button on the product page to see which one of our Thule authorized retailers has the product in stock.
