I'm not sure if the Coke distribution person is bringing bad/old stock or if Diet Dr Pepper has changed something but all the cans I get have no carbonation and taste flat. It's been like this for months now. Even the ones I get from work (which is 25 miles north in another city) is the same.

The sale I had been enjoying ended and the price of the different containers and sizes went up. It was at a point where I was going to have to get less. I am a Dr. Pepper addict and getting less was unacceptable. Then I found this 12-pack of .5L (16.9 oz) bottles. The price is better than the others so therefore the winner.

I am a huge diet Dr Pepper fan. I go through these 12 packs every 2 weeks or more. This last patch was completely flat. No fizz in any of the bottles I opened in any of packs. Has to have been a bad batch or it sat in the heat for an extra long time.

There’s no comparison! A cold Diet Dr. Pepper doesn’t get any better! The price is …OK. I remember when the deals were $1.99 per 12 pack! Now I’m giving away my age! Lol! Keep up the great work manufacturers! I LOVE you ALL! A Diet Dr. Pepper makes me so Happy!

Prices just keep getting worse for all products and And we as consumers are eating the taxes and price increases not big corporations with billions as the world gets worse all grocery providers are making it harder for us to afford much stuff anymore

Diet Dr. Pepper is the best diet soda out there in my opinion. I really love the Caffeine Free Diet Dr. Pepper flavor the best (both for taste and health too), but I can't buy it in a local store anywhere around. And the cost to order those online is just outrageous so I just have to stick with the plain /original Diet Dr. Pepper. Just wished they were kept in stock better.

Dr Pepper, the diet Dr Pepper has always been my favorite drink. I used to drink the regular Dr Pepper and then when I got older, I had to watch weight so that diet Dr Pepper taste dislike the regular Dr Pepper and I love it. I will always drink Dr Pepper till the day I die.

I buy a lot of Diet Dr Pepper, and have been for several years. Lately the quality control of canned Diet Dr. Pepper has been eroding. In summer of 2025 I has recieved sealed cans that were completely flat (no carbonation, can was squishy, not pressurized), I have a sealed completely empty can, and the worst is cans that look/feel correct but the taste is "off". I suspect this is a regional issue with the local Diet Dr Pepper factory serving North Texas, not a Walmart issue.

I don't like the fact that during the summer months, you can drop the price down to almost $10, then when summer is over, you jack the price up$3. You should keep the summer price all year long. It seems that pepsi and coke have periodic sales, but never Dr Pepper????

I have been getting a good many cans that feel real thin ,bend by just putting my fingers on it .. Then when i open them they are flat no fizz whatsoever .. i will take more pics when i get more if u like this one isn’t doing it as bad as others have but do u see the dent? I can’t put a video on here
