But clearly that was a fairly dubious tie-in, unrelated to Radio Shack's original business of being a go-to place for computers, audio and TV gear, etc. If it had still been profitable to sell electronics from small storefronts, they wouldn't have needed a Sprint to try & save them.
From
http://www.phonearena.com/news/Sprint-is-no-savior-Radio-Shack-goes-bankrupt-again_id91901 :My comparison to Netflix first & later streaming video killing local videotape/DVD stores was that small storefronts (or even big storefronts) can't offer the vast choice & nor volume prices available online (remember that even when Netflix rented only DVDs & not streaming, you still browsed their selection via the web). Similarly Radio Shack can't compete in the hobbyist part market in the face of easy online access to the likes of DigiKey and Mouser, nor can they compete in the consumer electronics market in the face of huge online stores such as Amazon (which is where I have bought most of mine the last few half-dozen years).
