Cheapest groceries in/near Mission Bay?

Just moved to Mission Bay. Don't have a car. Where do y'all get groceries?? I'd been a Walmart+ girl for years but they don't deliver here. The Safeway is scary and Gus' prices are ridiculous. I'm not fancy. I literally want cottage cheese and Greek yogurt for sub $7.

Any store/grocery delivery recs that don't hike up prices?
