In NYC, where I live, we have bodegas. They’re like your local corner store, stocked with a fresh meat deli and a sustainable mix of perishable and non-perishable items in about 800-1000 square feet. It’s mostly for those items you need in the moment and don’t want to go far to get. Unfortunately, you’ll only have as much choice as space will provide. This is like Gemini for me.
A conventional supermarket would be like Libra. It’s bigger and you have more choices–with more opportunities to be indecisive too. The grocer/owner is in partnership with you to provide your needs, but it’s definitely a me (grocer) vs. you (customer) affiliation. I’m never paying nearly at cost as much as the markup. Everyone is in relationship, but there’s no matched intention other than to sell the grocer’s food at his/her/their desired prices and net profit.
A co-op supermarket would be more Aquarius. It’s literally a co-operative venture between the members who own, staff and shop at the market. There is a collective intention to provide the best possible food at the lowest possible cost to increase members’ savings, not just a profit margin. The downside may be a different level of variety than what you experience at a conventional market and not as much of the convenience of being nearby. Of course, I think of my old food co-op in Park Slope when I think of this model.
