I worked there ( at a Canadian one) about 8 or 9 years ago (just before the Canadian one became "THE SOURCE BY CIRCUIT CITY" when the lease on the Radio Shack name came up for renewal in Canada) and one guy I worked with (who had been there since it was Tandy Leather) said they used to make employees memorize resistor colour codes. When I was there, we had to memorize Rogers cell phone plan particulars instead. It had basically become an over-sized cell phone kiosk. Their assets must be worth something - that have a lot of prime real estate in high-traffic retail areas.
