Unfortunately, the way some big food retailers (food stores) buy is through large sources, versus small producers. This reinforces the factory-farm model.

Locally we have two main supermarket chains. One will only buy from producers who can supply all of it's stores. The other allows it's stores to purchase products from small suppliers.

There are a few small meat/produce markets. And there is much marketing talk about buying local and from small producers. But, mMost of the small outlets do not do well at getting and keeping regular customers, as many people seem to prefer to purchase all their food at one source, often a large supermarket. Possibly price is also a factor?
