Input:
User Review: Recently purchased a nook HD for my daughter for Christmas. We are not happy with the device, and the customer service at B+N leaves A LOT to be desired - especially compared with Amazon. I have been so discappointed in their lack of customer service assistance with this device that I wanted to return it. Amazingly, B+N does not allow returns after 14 days - even at Christmas. I think this is inexcusable. How many other parents are going to have to deal with this problem? How can a company not even consider extending the return policy at Christmas time? Even Apple, a company well known for their less than stellar customer service, understands that sometimes electronics purchased as gifts for the Christmas Holiday are going to be returned and extend their typical 14 day return policy to be 14 days after Christmas for ALL products purchased between October and December 24th. I will certainly never buy another device from Barnes and Noble. I find this policy to simply be unacceptable, and hope that potential buyers of this device consider this next year when considering their gift purchases!
