I started using Grassoil Cologne by Jovan over 30 years ago and loved the fragrance and thought it to be both unique and inexpensive. I have never gotten as many compliments on any other cologne before or since. I have no clue why Jovan discontinued it, but hope they will bring it back in the near future. It is now a collector's item and goes for as much as $260 for 3 ounces, if you can find it. There are some ebay sites which offer it for $70, but the color looks wrong to be grassoil, which was a nice green. Their offer looks light brown. I don't know if a fragrance can "sour" or "go bad", but if not, then it's a good buy regardless of the color.
