Tip 51: When to buy food items at convenience stores
Some convenience stores sell some items at reasonable prices such as eggs, bread, and potatoes; however many do not. Milk sells for 50 cents to $1 more per gallon than at a grocery store. You'll get better prices at a grocery store, plus there are healthier food selections available as well.
Like all rules, there are exceptions. If you have run out of milk and need some to get the kids off to school, it may be worth the money to pay an extra 50 cents to get it at a nearby convenience instead of driving further to get to a grocery store. It costs about 20 cents per mile to drive a car in town, so if the grocery store is a few miles further away that the convenience store, you may be better off driving less and paying more in some situations.
