The local Radio Shack's here are already remodelled over. There's a handful of electronics things left but you wont ever find the kinda sales staff that was knowledgeable. Heck I remember one old salt giving a customer tips on soldering and stuff.
I used to work at a Radio Shack part time for about a year. Right around 1990, I think...whenever the 486's first started to hit. I remember we were knee deep in computers, selling them like crazy...and radio scanners were the craze. I recall special ordering tons of special frequency crystals, various radio parts, etc. Thair parts dept was really quite awesome...you could get almost any part for anything electronic.
We had a Tandy Service Center up the street from us. Those guys were the schnitz.
Now that im into electronics more, its a shame these local resources are all but gone.
As for Sears...
Up til a few months ago, I'd work a few hours on Saturdays. Big screen tv dept, so it was low effort, nice comissions

Sears is being whammied by the Walmarts. However, to their credit, they will pricematch all those big guys to get you to buy your TV there. And I much prefer the Sears Service Plans than "whatever third party we can scrounge up" that others use.
But Sears has this odd concept of putting 20 people on the sales floor lately. That's just too many sales folks...so I got done.
I remember, back as a kid, looking at the Sears Christmas Catalog and drooling at the go-karts and minibikes!
