Purchasing our products from distributors is a good solution when you are not able to meet our 10,000 lb. minimums.

You can order smaller quantities, improving turns and reducing cash flow.

You receive the product sooner, distributors are in your area that carry our products. You could possibly have your oats that same day or weeks sooner than buying direct.

If purchased outside the US and Canada, you are purchasing stock in the same currency. Distributors will be purchasing stock in different currencies which can often have major implications if there are any big fluctuations in foreign exchange.

You pay less in shipping costs. Shipping in bulk is less expensive compared to individual bags in quantities less than our minimums. A distributor will pass this cost savings to you through a lower delivered than buying direct.
