It feels in effect silly to go into something called “RadioShack” and ask if it carries radios–predominantly when the answer is no. (One of the locations, in a mall otherwise dominated by stores such as Aeropostale and Victoria’s Secretive, had shelf after shelf of diodes and transistors for sale–I be astonished question when was the last time anyone bought any of those?–but no radios.)
I also tried two Best Buys, and a Butt. None of them had a straightforward pocket radio with a built-in speaker.

All of these stores did have cognate products of several sorts I wasn’t looking for, such as tabletop iPod docks with built-in radios, clock radios, and live through radios. I also saw more hand-cranked Etons in a variety of sizes–boom box apparently being something that people think of as an emergency supply rather than an everyday penury.
At one Best Buy, I even saw a Walkman with a tape player as well as a built-in radio–a classic implement I didn’t know was still extant.
