Perhaps someone at Pepsi should have through through their promotion with Amazon a bit further before signing off. Wal-Mart and Target–who have been selling music a little bit longer than Amazon and not coincidentally, also sell a lot of Pepsi–are reported to be a little miffed with Pepsi for spending their ad dollars driving sales to an internet competitor, instead of sending customers into the racks at their brick and mortar establishments. On the other hand, if Amazon finally complete their research into the direct download of caffeine and heavy processed sugars, who will need to go to the store anyway? [Financial Times]
