The coops in my American city are usually the more expensive option than the chain grocery stores. They pay their staff fairly (because the staff own part of the business) which is great, but saving money for the consumer they do not.
I just don’t think a coop can be cheaper than a larger corporate entity that can purchase at huge bulk discounts for their many stores. Healthier? Sure. More ethical? Sure. Similar costs or cheaper? Nah.
Just have to give them a few more months to continue bombing hospitals and schools and any and every building. Once they do that, a cease fire is possible.
