I don’t know much about them but I like the idea and I’d be more inclined to use one.
We have the Co-op in the UK and it’s a household name. They run a bank and local shops but I think do more than that. They’re not employee owned though, they’re consumer owned. I’m not entirely sure what that means but I remember you used to be able to walk into a shop, pay a small amount of money, and then join. Each year you’d get a small amount of money depending on how much profit they’d made.
Feddit.uk is good if you’re in the UK. Then you can switch to Local and see lots of UK stuff.
