I found this problem with a lot of things. So what I found that works the best is to buy like this in bulk ; not from the bins, but go to the special orders desk or just ask a clerk that you would like to buy whatever it is you want in bulk. I don't like a lot of packaging, but usually the packaging can be recycled. Anyhow, when I pick my stuff up, it's in a big box, and then inside that box are a bunch of individual boxed items of what I want. THis way it is cheeper and I get a lot so that I can share with friends or neighbors. Does this make sense? It doesn't go rancid because of how it is packaged.
