I like the fact that it's a diet soda (no calories) but leaves NO aftertaste like some diet sodas do. on the negative side, ALL brands of soda are way overpriced these days. Every time I go to buy more, the price has inched up again and I'm tired of being gouged as the register. It's almost enough to make me seriously consider not drinking any soda any more.

I would recommend Mountain Dew diet from Walmart. Their prices can't be beat. I would recommend that everyone gets a subscription to Walmart shopping thank you, Vicki Martin.

Diet Mountain Dew – same great taste!

Diet Mountain Dew is one of my family’s favorites. It has the same great Mountain Dew taste with 0 cal and 0 carbs. It does still have caffeine so I have to be careful not to drink it too late in the evening or I can’t fall asleep!

I only drink diet Mountain Dew . I just wished the prices weren't so high. It makes purchasing them difficult at times. Don't smoke, don't drink alcohol etc. Dt. Mtn. Dew is my go too. And at the prices for 12 packs and cases it makes it next to impossible at times.

Get Rid of the Dyes!

I'd prefer Pepsi do away with all of the synthetic dyes... No one cares if it's yellow, we only care about the taste. Please follow in the path of Doritos and their Simply NKD product line. They taste the same...

An Arm and a Leg

This is a basic grocery for me. I buy it if I don't have to cut-off an arm to be able to afford it since beverage companies act like they are going broke. The price of all soda went up big time during the pandemic because of supply chain issues, but the supply chain recovered three years ago and the beverage companies have not raised their worker's wages or lowered prices even after lowering their costs.

Great in every way BUT too expensive.

Good but BAD!!!! We love these in every way but one: - We love the taste that does not taste like a diet drink, - Cans make them very cold and stays cold for a long time, - They are low-calorie, they have kick! Mountain Dew was the original energy drink withs its caffeine content that still gives this diet drink kick even without sugar. The BAD: I used to get these at the start of COVID for $4.99 when on sale, now on sale they are $11.99. When they are not on sale, they are $13.97! My family buys 5 to 6 of these per week! We are cutting back and looking for alternatives. :( If we use the USA inflation rate from 2020, these 24-pack of Dews should only be $6.23 on sale. The dollar value has been lost. I clicked recommend here, only because I am still searching for alternatives. --2006-02

Walmart is overcharging for this item

Just be aware you are being overcharged for this at Walmart. You can go buy this at any other store for 25% less. Most places this and the 12 packs you can get a better price most the time even getting a free pack if you buy a certain amount. Tired of Walmart overcharging for items.

Food is too expensive! This is dog pile greed!

Way too much money! This product has been raised up almost a full 40% from five years ago! Don’t start getting caffeine from soda pop. You can buy caffeine pills way cheaper.
