Internet interface does not allow for smooth transactions involving items by weight. Please call for assistance during normal business hours. We would be happy to create a Special Order Grain Bill just for you in our system and add it to our website so you can order it from just about anywhere there's internet service. Here is a list of the grains we have in stock. Quantities are limited. When you call we will be happy to check our inventory. Thank you for your business. 518-798-2337
