If you scroll down on that page where they disappeared from, you will see a little line of print that says something like: Click here to see items that are out of stock". when you click, it shows you a list of the things you are looking for. They also have a link somewhere nearby that says click here if you want us to send you an email when the items checked are back in stock. That has worked for me twice with fragranceX when ordering Tabac products.
Now for my PS: I didn't/couldn't force myself to really like the strong fragrance of Tabac, but of course the performance of the product is absolutely top drawer. For that reason, I have rid myself of my Tabac, and am patiently waiting for the day that we can purchase the Irisch Moos products anywhere that sells qualilty men's shaving products, like fragranceX for example.
Thanks for the tip. Awaiting email notification for the refills!
