I learned the basics of electronics with one of those "breadboard" kits ...
Overall, they were a little expensive and a lot of their stuff was just rebranded ... For example, the scanners were all Uniden, just rebranded ... The CBs were the same ...
I worked in one of their stores during peak, and their markups were insane ... Each store was built independently to the Tandy corporation ... This made it to profit levels, one to Tandy, and one to the store ...
A good example, a simple watch battery, it cost them about 14 to 18 cents, but they charged $4 in the stores ... That was the cost that Tandy levied to the stores, so what did it cost Tandy; probably about a dime ...
Everything in that store had the dual markup ...
The first one being what Tandy charged the stores, then the second being what the stores charged us consumers ...
They definitely had profits down to a science ...
PS; I really miss Bradlees as well ...
