I'm wanting to pick up a few soap samples. I know I can go to many artisan websites or I could also go to some vendors, but is there one central place that either specializes in or has a larger selection than any other?
Yes. I would recommend trying TSD. I received 2 samples last month. They have a pretty good selection of good quality soaps and the samples come in a nice small lidded container at a very reasonable price.
There's also Menessentials (Canada and US, I believe), Shavedash (N-Ireland), Connaughtshaving (England).
Maggard's, Garys sample shop, IB. Maggard's has a nice selection of samples to choose from, and you can get many shaves from one. Samples are great so you don't get stuck with something you don't like.
