I'll let you in on a little secret. I bought 250 Mach 3 blades off ebay in 2004 for $192.50 (.77 apiece). Walmart is selling them for
$2.89 apiece. That would be the equivalent of 250X2.89 = $722.50 today. BLS inflation calculator says $192 is only worth $243 today. Guess who is getting f'd in the ass (hint: you guys who buy Gillette)? Not to mention I bet the quality has gone down in the past decade since Gillette has shareholders to appease.
These razors have gone with me to 3 different states and to 6 different places in the past 11 years. They are so small that it's not a big deal, and if I have a buddy stay the night who forgot his razor I got him covered. Still have 48 left over, one blade seems to last a long time - at least a month and I shave about twice a week (telework a lot). My burn rate (including giving some to friends) is 1.5 razors/month, so it will be another 6+ years before I have to worry about razors again. I remember my dad was like wtf when I told him I bought 250 razors to beat rising costs that Gillette would inevitably pass down to us. Now he thinks it was a great idea.
In 2021 I'll probably check out Murkur, or just find the cheapest supplier of Mach3's and buy bulk again which should should last me close to retirement age. Actually, I may try Murkur now and just buy bulk razors (500-1000) if I like them. Never have to worry about buying razors for decades, and who cares if they raise prices.
