Shop like you would if you were staying home. When you’re on the road, look for some of the cheaper places you normally shop; like Walmart, Costco, Aldi, Walgreens, Trader Joe's, dollar stores, Kroger supermarkets, Target, and Sam’s Club. These chains run websites that show their locations. Walmart even sells maps and road atlases that shows its’ locations. A road trip doesn’t have to be a budget breaker. A little imagination and common sense can help save money on the road.
