Can you buy books off the barns&noble website with their gift cards?

I do not own a credit card and the nearest barns%26amp;noble is an hour drive, but I have a gift card from them $100. I was wondering if I could buy a book off their website using my gift card.|||Check the card and read the back like the fine print and it should say for use at Barnes %26amp; Nobel and www.bn.com. Hope this helps! Same thing for any gift card by the way.
