A Staple in our Fridge

Chelsea July 18, 2026

Diet Mountain Dew is one of my family's go-to drinks, so having it in a 12 pack of plastic bottles is perfect. The bottles are convenient to grab and take on the go, and they stay fresh and fizzy. The flavor is always consistent, and it's the perfect refreshing drink when we need a little pick-me-up. Definitely a staple in our house and an easy 5 stars!

My Go-To Sugar-Free Soda

JudithWord June 17, 2026

⭐⭐⭐⭐⭐ As a Type 2 diabetic, I stick almost exclusively to sugar-free drinks, and Diet Mountain Dew has been one of my go-to sodas for years. In fact, it's pretty much the only soda I drink on a regular basis anymore. I've gotten away from dark sodas, and I much prefer the citrus flavor of Mountain Dew. That said, I actually prefer the Zero Sugar Mountain Dew version over Diet Mountain Dew when I can find it. The flavor is a little closer to the original in my opinion. Still, this is a great option, especially when Zero Sugar isn't available. It's always crisp, refreshing, and gives me that soda fix without the sugar. I'll definitely keep buying it.

Healthy?

Terry April 26, 2026

I don't know but I do love this drink and this plastic bottled version is an outstanding value. Crisp and refreshing, I would drink several cans or bottles a day if I didn't try to limit myself. Especially in the hotter months. There is nothing quite like an ice cold Mt Dew on a humid July day. It is my favorite soft drink.

I g had to stop drinking regular Mtn. Dew in 1983, due to diabetes, and I had to get used to the diet version. I grew to love it and my home will never be without it, I like being able to get 12 packs as they are easier to carry and store them.

Refreshing soda, price is concerning!

anonymous July 18, 2026

great refreshing taste doesn't have the diet taste like most sodas. My only complaint is just a couple weeks ago y'all had a rollback price and now I have reason to believe that you've jumped back up even higher then the price before! What's up with that?

Disappearing product

Alice April 12, 2026

What annoys me about this product is that I want to purchase 24 oz bottles. I used to be able to do that in this application. Then the option just disappeared. BUT 24 ounce bottles are available in store. They are on the shelf when I make a special trip to get them. Don't you WANT me to be able to easily purchase the exact item I want?

This item was not delivered. Regular Mountain Dew was delivered instead of Diet. I also was missing a 2 lb. box of strawberries that I ordered and was charged for. I would appreciate it if these errors were corrected as soon as possible. The pop is fine even though I'm a diabetic.

When I opened all 3 sealed packaged bottled Diet Mtn. Dew's to my surprise they had the Diet Mtn. Dew label on them but were sealed with a black cap. I remember the black cap was for the Zero Mtn. Dew. Plus, I opened 7 bottles of these bottles and they definitely did NOT taste like Diet Mtn. Dew. Sounds like a quality control issue to me. It surely did not satisfy my soda craving for my favorite soda of Diet Mtn. Dew.

the diet mountain dew that have the black lids taste different than ones with bright green lids. they are flat, and lack the sparkling taste of the original diet dew. the bottles and ingredients are the same, but the quality is Not. the last 2 times ive ordered online for delivery, i got the black lids, and i kept the first 12 pack, but returned the rest. just not the same.
