Hello,
Welcome to the boards. I believe that '1stPerfume' still has most of the line of Gucci Nobile products, but their prices are quite steep. So, if you REALLY wanted it, you could get it from them. Otherwise, I believe that 'Nobile Royalty' by Alexander Da Costa is very similar to the Gucci Nobile. It is available at 'PerfumeBay' for only $20. Hope that helps.
