A few readers have noted that 20oz Pepsi Bottles are not the only location that you can find the iTunes/Pepsi 100 Million Song Giveaway.

7-11 convenience stores are carrying specially marked (Apple Logo'd) Pepsi cups. Some photos of the cup are shown here.

Another reader notes that their local gas stations carry the same Pepsi-iTunes cups.
