Barnes & Noble gift card does not work with eBooks

Some guy known as Dave had a Nook pre-ordered for him from the local Barnes & Noble store, picking up a $100 gift card in the process to kickstart the eBook collection. Unfortunately, when the bloke tried to buy a few books virtually, he realized that the gift card was useless, and this without having the staff at Barnes & Noble inform him earlier. Hopefully not too many people will suffer the same fate this holiday season.
