Pepsi is a household name, and Diet Pepsi is no different. This pack of 4 330ml cans are ideal for refilling vending machines, selling in canteens or just to have in the home. The zero-calorie soft drink substitutes sugars for sweeteners and has the same light, crisp and refreshing taste of Pepsi. Best served cold, each can will refresh and revitalise with 35mg of caffeine per 330ml can.
