Theve been dead to me for over 15 years. Ever since they stopped selling useful electronic and electrical components there was no reason to go in one. Circuit City (RIP) or Best Buy had much better prices and selections.
My father in law rented commercial space to a Shack for five years. Just last year he kicked them out because they were a complete failure of a business. Sent 'em packin. It was funny too because they assumed their lease would be renewed but the owner was a d*ck and always late with the rent so my father in law didn't tell them until the last minute. They had about three days to get EVERYTHING out and find someplace to keep an entire stores worth of merchandise.

RadioShack's days should be numbered. They are much higher priced than their competition, and unlike the old days, their staff is more expert on cell phones than on resistors, capacitors, and general electronics.
