This deal feels right. Both companies seem to be committed to customer service as their number one goal. Based on what I've been reading about Zappos, Tony & Co deserver this. Great company, great management, great culture, great news!
EDIT: I'm curious about the downvotes. I think deleting books of customers' Kindles is in direct opposition to customer service being their number one goal. I have a feeling Amazon isn't all that interested in customer service and I don't remember any super positive things about Amazon culture. What am I missing?
