On our product pages, if we don’t have stock on an item, you will see that it is “available on backorder.” Usually this just means that we don’t have that item built up and ready to ship immediately. In such cases we can usually make the item up in a day or two.
Occasionally we are waiting on materials to make a regularly stocked item and that may translate into a longer delay. We generally will post a notice on the product page warning about such situations, but if you have made your order and we expect even a few days delay before shipping, we will advise you promptly, giving you the option to modify or cancel your order as you see fit.
