The last time I was at Costco, they seemed to have discontinued a lot of their nuts. Well, it turns out they hadn’t discontinued them, but are switching over from jars to bags, which use a lot less plastic. So save all the jars you have, for they shall not pass this way again.
Unfortunately, while I can recycle the jars here I can’t recycle plastic bags. So I’m not sure how environmentally friendly this is.
Most of the nuts I buy there already came in bags, so not a huge deal. However, when I was there last weekend I was thrilled to find a new offering (in a jar, oddly enough) - salted “snacking” pecans. I haven’t opened them yet but they look to be very nice quality.
