Razor blades are a high-density, high-margin item that is never going away. The prices are just going to go up. Feather blades (the best in the world) are made in Japan and are not going anywhere.
That said, prices are definitely quite elevated. Checked my order history, and when I first starting buying Feathers they were $23 a pack and my order the other day was $40. Nearly double. I keep a couple years worth on hand so I'm g2g for a while, but if the prices keep going up I'll have to start reusing blades. Normally I use a fresh blade for every shave. The horror.
BTW if you shave, and you don't use a double-edge razor, you need to get a double-edge razor. Even with today's prices my cost per shave is around 50 cents all inclusive. Last vacation I grabbed a Mach 3 and it felt like shaving with a cheese grater.
