If anyone is curious, there are definitely a few stores left with the RadioShack brand, though most if not all of them are independent of any centralized organization: https://www.radioshack.com/locations

The ones I’ve seen sell mostly phones and toys now. They might have a very small selection of components in a corner.

Phones are radios, it’s right there in the name of the store.

There are also RadioShack stores in Guatemala, El Salvador, Honduras, and Nicaragua
