I purchased 4 cases of 24/20 oz bottles of pepsi from Sam's Club, and more than half of them were flat. we have been purchasing pepsi products for over 30 years and have never had such a large amont of bottles turn up flat, i would say more than half of the bottles were flat, please tell what you guys are doing that make them taste like crap, we didn't drink them after finding out they were flat, and no we can't take a picture of a flat bootle of pepsi, just doesn't show how flat they were. we would like to be reimbursed for at least $22.00 due to the bad taste, Please find the problem as we really like pepsi better than all other soft drinks, thanks Ken Malding
