Last time I went into a radio shack last year, I needed a USB A to mini A to charge my MiFi hotspot, I had left my cable at the airport. Its a pretty ubiquitous cable, but when I could not find one and asked, they were like "Oh we dontt carry those anymore" How can you not carry one of the most common USB cables in the World? No matter, their other cables were > $20 anyway. I ended up getting the cable at WALGREENS!! for $4.
