Unless I'm missing it, the only way to view someone's wishlist is to be logged on under the same account. If there was a way to share a wishlist with other people and give them the option of purchasing a book for that person it would generate more sales. Another nice touch might be to set up a delivery date and an e-card notification of the gift. Every Christmas I think of this when family/friends ask what I'd like.
Have you tried the "share" option available on wish lists?
I dont actually know how this works but could be worth looking at
