About the time they got rid of the hard plastic cashew jars and switched to the bags, they also started selling a (more expensive) glass jar of cashews.

So for me, it does cut down on the plastic, since now I just refill the glass jar with the bagged cashews, rather than needing to buy (and dispose of) the plastic jar every time.

I might feel differently if I was actually reusing the plastic jars for something but I really wasn’t (not after the first few, anyway).
