iTunes-Pepsi Bottles Delayed

USA Today reports that the Pepsi-iTunes promotion hasn't delivered on a large spike of digital sales -- yet.

The reason is that the bottles have taken longer than expected to get into general circulation.

According to USA Today, they only arrived in New York last week and have yet to show up in Los Angeles.

Meanwhile, Pepsi expects a 10-20% redemption rate for the promotion, which could bring Apple's total sales to date up to 75 million from the current estimate of 52 million songs.
