Convenience stores are just what their name implies -convenient when you run out of something. Their sometimes higher prices are the cost of that convenience. Make a list of what you need to purchase so you don't waste miles running back to the store for forgotten items. Everyday common sense prevails when grocery shopping away from home. Most grocery stores run specials and print coupons in newspapers on Thursdays and Sundays.
Many markets also have racks of discount coupons.
Since stores vary widely in pricing on the same foods in a single area, ask campground management the best stores at which to buy food. Check unit pricing on grocery shelves to see what brand and size is the best deal. Local roadside stands sell everything from farm raised fruits and vegetables to honey, syrup, plants, and juices-all at great prices. Many towns have farmers' markets at least once a week selling delicious home baked goods and fresh produce and meats. In some areas, you can visit farms and pick everything from strawberries to apples.
