We purchsed a large order, which was received within a week. Unfortunately, one bottle contained a capsule that had broken open and spilled its contents into the bottle (that's happened to all of us one time or another.)Upon receipt of photo of product, the company immediatle replaced the entire order. now THAT's great customer service!
