Good trash bags but would like this sent in 30 gallons at not a huge price
Style: Citrus Spritz
Even though I thought I bought 30 gallon not 13 gallon I still like the product . We used a couple of rhe bags . It worked out some9ne else needed this size so we just sold it to another and I have to reorder NY size downfall I guess they don't make 30 gallon in this scent that part I'm sad about its the one scent that doesn't bother my senses like the others do.

Good, could be better.
Style: Fresh Clean Breeze-Black
Nice scent, but not as "heafty" as they used to be. They break a lot more easily.

Strong, reliable trash bags we consistently reorder
Style: White Pine Breeze, Size: 50 Count (Pack of 1)
These Hefty Ultra Strong 30-gallon trash bags have been a dependable household staple for us and are set up on Subscribe & Save because they work consistently. The bags are thick, durable, and hold up well to heavier loads without tearing or leaking.
The drawstring closure is sturdy and makes tying and carrying the bag easy, even when it’s full. We use these for general household trash as well as occasional heavier cleanup, and they’ve held up well against punctures and sharp edges.
The White Pine Breeze scent is noticeable but not overpowering. It helps control odors without smelling artificial or too strong.
Overall, these are reliable, heavy-duty trash bags that do what they’re supposed to do. Since they’ve been consistent and trouble-free, we continue to reorder them and have no reason to switch.
