I personally have used NG for the past 6 years. They are my main FO supplier. I only go elsewhere if I need something they don't have. I have been very happy with every oil I have ever purchased from them. I've tried other oils from some other suppliers and they have been decent, but the levels of customer service that I've gotten from Debbie and her staff at NG are unsurpassed by none, so I just keep going back. BTW, If you get your order to them by 11am it usually ships the same day! HTH Greg
