It's not just brick and mortar stores, it the entire supply, the web stores as well.
Dovo, Thiers-Issard, all of them are back ordered, in some cases years! I know of one place, that has over 800 razors on order for the last year, and they maybe get 6-10 at a time. And when they arrive and are made available, they're usually gone within hours, at the most a couple of days.
One web store had a nice TI Wolf and Sheep 6/8 that I have, they got a few more in a couple of day's ago, they were sold out in hours. Even the Dovo Best Quality razors come in and they're gone fairly quickly.
I waited 8 months for a new Dovo Bismarck, gave up and found a virtually brand new one with a 3" strop on E-Bay. So, as the saying goes, I wouldn't hold your breath.
So, this isn't a local phenomena, it's a world wide thing, and quality control issues for the big makers have become an issue.
One place though you're sure to get a blade, and they make nice ones, is Revisor...my two cents!!
Cheers!
