One of the fastest growing food markets in the USA is Save a Lot. Both in FL and MI I've found new chains of Save a Lot sprouting, especially in the smaller towns.
If you haven't tried Save a Lot yet, you've been spending too much on groceries, particularly staple items. This Palmetto store has many Hispanic food items. The produce is local and usually pretty fresh. They also carry fruits and vegetables not in season for a reasonable price. The can goods selection is quite varied, again for low prices. The meats are just average, in my opinion, so I pass up that. Dairy foods, especially milk, is always up to date and cheaper than I can find anywhere unless there's a sale. I love stocking up on the frozen vegetables, especially the stir frys.
Unlike many of the bigger supermarkets, I've not had to wait in long lines. If it does get crowded they have enough cashiers to open more. They accept all credit cards except American Express. Be warned that the clerk does not bag your groceries. Bring your own plastic bags or use their free boxes.
I'm always amazed at my total bill. The low prices bring me back every time.
