Wow, so many people trash Walmart for try to get the lowest price for their products, yet it seems to be ok for Apple to try to undercut the market, by a large amount.
Way to sweep those generalizations. Plenty of people are supportive of Walmart (follow the money, vote with the wallet), and plenty of people are trashing Apple for this.
TallManNY has the best explanation: Pandora is operating at a loss paying $0.12/hundred, so obviously offering that (or more, like others operating as walking dead) is a non-starter. Around $0.10/hundred is the likely break-even point, and between seeking an actual profit & starting at a viable point for negotiations, $0.06/hundred is a good place to start. That's not "undercutting the market by a large amount", that's pursuing a viable business plan.
