Nobody will ever convince me that a $50 soap is worth the performance compared to the far lower cost options available; i.e. Stirling mutton. Heck, i'd say his beef soaps are good enough. This is why Stirling will be around for a long time- they've carved out a business model for themselves and have stayed the course.Stirling is generally considered cheap, not high end. It's good soap, don't get me wrong, but one of the things people really like about it is that is very fairly priced.
You may or may not know that there are people on these forums that are spending upwards of $50 and even $60 or $70 on a puck of shaving soap.
But- i keep in mind that this is a hobby, so i don't know knock anyone for spending X on a soap that isn't going to make much of a difference in performance in the grand scheme of things- ultimately you want a great shave and there are many products that will get you there, Williams mug soap included.
