I needed to replace the cord for my Nook so I took it with me since I really had no idea which kind of cord it was The gentleman who helped me took one look at it and left me directly to them. Can't get much better help than that!
I have an older phone. Many stores do not carry cables for older phones. Staples does. I was in and out of the store in 5 minutes and started charging my dead phone as soon as I got home. Whatever you need Staples has it...always.
