With gas prices reaching sky high, it has become something not to be wasted. If you go out to shop, you are taking the risk of being stuck in traffic, and you have to wait for a parking lot to be vacant if all the slots are full. Not only that, you can't be sure that you'll be able to find everything you want in one store, you might have to check out at least ten places on end. So, why go to all that trouble when you can save gas and energy by shopping from home.
