Hello Victoria and welcome to Permies!
I hear what you're saying about zero waste shopping being expensive, but it doesn't have to be. I run a little shop on Skye and we were lucky enough to get a grant from Zero Waste Scotland a year ago to extend the package free offering we had (see
my original thread). Because we are a small rural store, the market for organic wholefoods is not big enough to justify my stocking that range only, so I chose goods that were mainstream, retaining the organic option in packets. This is sort of a win-win I think. The zero waste option, because I was buying catering packs turned out cheaper, and the people who chose not to use the zero waste goods, get a better grade of product also. In an ideal world of course we'd only stock organic, locally produced food, but then it would be only a fantasy shop as it would quickly close down!
I notice your website link Pick Ethical. I must see if I can register with them, we're not just zero waste of course but a full convenience store that tries to do better.
