I saw this on an Instagram reel today and it works. I forget the fragrance creator that shared this or I would shout them out.
If you go to the Penhaligon's website, do a search for samples, and then click on "view all products", you will see a bunch of samples that are available for free (you pay for shipping, however).
Many samples are sold out but many others are not. It's worth checking back every so often. I ordered up a sample of Halfeti and the new Blazing Mister Sam Intense. I didn't realize that this was a thing. Check it out if you're interested!
