I've had two different DPC, one about $45/mo, now with one about $30/mo.
Both combined are still less than I would pay in any marketplace.
It's nice to be able to just see your doctor without worrying what it might cost. A large list of simple procedures are covered, and tests cost next to nothing. It's a health subscription to an actual doctor who can be just as cost-conscious as you are while still incredibly knowledgable and invested in your health.
