Each 12 oz can is equivalent to one cup of coffee. Since I don't have any other caffeine intake, this small can is perfect to energize throughout the day. The original price was fabulous and competitive with local store sales. The triple price of other online vendors takes away that competitiveness, so while I recommend the product, it can be purchased for a lessor price at local grocers
Love this stuff. The blueberry flavor is delicious and refreshing. No aftertaste. It contains 68mg of caffeine so it shouldn't give you caffeine jitters even after drinking another caffeinated drink such as coffee or tea. I've bought these a few times from Amazon and each time they were packed well and the cans were not damaged at all. Great price too if they are offering the coupon/promotion. The vending machines sell these for a little over $3 for a can.
