Rare doesn't really mean 'extinct' if that is what you inferred and hence you decided to impart the precious knowledge. I am sure it is available at most shops. I am glad you decided to participate however to a seller this is potential derailing of the thread. If I am scamming someone you have the utmost right to inform the buyer but not otherwise.
If you have concern about authenticity of the product then feel free to discuss further otherwise kindly avoid derailing my thread.
Your cooperation would be highly appreciated
