There are several of the great vintage Crabtree & Evelyn shaving creams listed by a seller named kristinalambert at $69.99 each plus shipping, but she accepted my offer of $40 for a large jar of one them that she had listed at $124, so I'm pretty sure she would accept an offer of around $25-30 for one of the tubes.
If you're looking for a good silvertip shaving brush, eBay has some Da Vinci Uomo 293 shaving brushes for sale. I can vouch that the one I have is excellent. I have two others of different models with quite exceptionally soft hair. These look very similar to what I have in stock. Excellent deal in my opinion!
