That's a good question. In it's heyday, RS had two types of stores. Direct corporate, and dealers authorized to sell RS branded merchandise. The last time I checked, all the corporate stores had shut down, but there were still dealers (like this one) that had the RS name.
The dealers tended to be in smaller towns. Often longtime, locally owned electronics (or CB/hobby) stores in which there was one store. Siler City comes to mind. There wasn't a single one that was in a larger city back when I worked there.
Anyway, the corporate stores are long gone (bankrupt in 2011ish? I dunno), but these authorized dealers still exist. Probably with RS branded cables. There's also still a website. So somebody scooped up the name. But I'm fairly certain the current version bears nothing to what we think of.
