this is just my opinion but I feel the shelf life of their oils are not very long like some oils I have received from other companies. I know some scents have longer self life than others but it seems a lot of the oils from AH/RE have went bad fast. I also have da Lime in da Coconut and it smelled off after 6months. I have coconut lime from Heaven Scent that I got around the same time & it still smells good plus it smells great in candles.
