Craftsman "name" was bought by Sears to use as their trademark for their line of tools. I believe for most of the early life of Cman they were generally available only from Sears. Fastenal sells them these days. I read where they are also sold at military bx exchanges. Also Western Auto sold them for a brief while. Kmart now sells them as has other Sears owned hardware stores.
Yeah there is a rack or two of CMan stuff at the BX. Just a small selection like a couple hammers, socket sets, maybe a wrench set or two and that's about it.
