The only exceptions are the physically large items that we cannot store in our main shipping location. These items typically take 2-3 days to ship. These exceptions are: car seats, cosleepers, bassinets, strollers, and rocking chairs.
Every item page says "in stock" or "out of stock" right by the product price, and if it is "in stock" there is an "add to cart" button visible. Immediately when the last item is sold, the "add to cart" button stops working, and soon after that, it will disappear and switch to saying "out of stock".
If you add items to your cart and wait a few days to check out, there is no need to wonder if your products sold out in the meantime because there is another inventory check when you click "checkout." Again, our system cannot process an order for anything unless it is truly available and ready to ship.
