I wish I could have the Radio Shack brand and funding to reboot it, because I would totally like to reboot the chain as what it used to be, before it tried to go all-in on cell phones and consumer electronics.
Radio Shack used to be THE place I would go for the random weird electronic knick-knacks that I needed.
I could find a basic selection of passives, various A/V connections, tools, etc.
But I would also reboot it with a bent towards the makersphere. Go in heavy on makerstuffs.
I would incentivize employees to become knowledgeable, by giving them the carrot of significant wage bumps for completing in-house certification courses like basics of electronics, basics of 3D printing, basic A/V, answer finding skills (because sometimes customers just need someone with better google-fu), etc.
Knowledgeable employees are worth more, because they become someone the customer can trust to give or to find informed answers to questions, and that brings customers back.
I think what I could even do is eat the cost of one or two units of each consumer-ready item for each store, as a store-owned sample that employees can proceed to use and learn the features on.
Literally, give the store its own toys for the employees to play with, that they can then turn around and use as a live demonstrator to sell far more effectively, because now the employees know what they're selling instead of just drawing a paycheck.
I think that would work extremely well.
The closest thing we have here in the United States now is Micro Center, if you happen to live within day-trip distance of a city that has one and you have a car that can make the trip, but Micro Center's hobby electronics section is an afterthought at best and it kind of sucks.
Micro Center is more all-in on computers, computer peripherals, and all things computer, which is their whole thing so it makes sense that maker electronics is an afterthought.
Just sucks that that's the reality now.
