Query: Great Product - BUT IT WAS EXPIRED!

Bene-Bac is a five star product for it replenishes the necessary bacteria that birds need for good health and is veterinarian recommended. However, the product I received expired August, 2010. It has the same Lot Number and Expiration Date that Diane reported in the previous review. Surely the stock people at Amazon could take a few seconds to check the Expiration Date before shipment.I called Amazon and they are refunding my money. They said a stock check would be made to remove any additional expired product. Because this is such a great product and the money I paid for it was refunded, I give this transaction four stars.
