You can assume that every item on our website is in stock unless otherwise indicated. But the best way to check if a particular item is in stock is to phone us toll free at 1-888-804-8820. You can also email us at firstname.lastname@example.org. When you place an order for seeds, you will be asked if substitutions are OK. If you say yes, we will do our best to find a product that is as similar as possible to what you ordered. If you say no, any out of stock item on your order will remain on our system as a back-order. When the product arrives, we will ship it out to you.
