Bought 5 cases of diet pepsi at 3 different locations on sperate days and every one was flat and bad tasting. They were dated july 15, 2007 and july 16, 2007. took the pop back to pepsi company in Kankakee Illinois and was told they wouldnt take it back I had to return it to each store and ask for refund or what ever. The company didnt want to make good on their product. read full review »
