The Walmart brand (Great Value) 5 oz tuna can is misleading. While their competitors, Chicken of the Sea and Star-Kist show on their labels that the gross weight of the can is 5 oz, they also show that the drained weight after removing the water is 4 oz. That way, the consumer know how much they are purchasing. Walmart does not put the drained weight on their tuna cans. When I drained theWalmart brand can, i got 2 oz of water so I am only getting 3 oz of tuna from a 5 oz can. Apparently there is no requirement for Walmart to provide the drained weight, but it is clearly misleading and a ripoff since the Walmart prices are not that much lower than the competitors.
