I don't know if anyone makes genuine "hubs" anymore, at least for consumer use. The last thing I looked at that said "hub" on the outside of the box, a really horrible cheapest-thing-we-could-find Linksys of about 2004 vintage, was actually a switch. (Confirmed via tcpdump.) Which was a bummer because we specifically *wanted* a hub for the application in question. (don't ask.)
It might be worth saying "switch" anyway just because most boxes say "switch" on them now, but there's not much danger of accidentally buying an ethernet hub. If they're totally computer-clueless a bigger danger is them walking home with a USB hub instead.
