I am going to be ordering some Oxine and I always like to stock up. I called the place I am ordering from to see what the expiration date is and they said it didn't have one. I checked on the bottle I have and there is not one on it either. So, does anyone know if expires ? I know it wouldn't last diluted but I'm wondering how long will an unopened bottle stay fresh? Alot of money to let it go bad or lose its strength. I was going to place my order online tonight so I can't call the company until tomorro, So I thought I would ask all of you experts !!! Thanks in Advance !!!
