If you live in a big city, you know how hectic life can be at times. Finding a place to park a vehicle when doing shopping or waiting in long queues when paying for groceries is just too much for some people. If you are willing to ensure these inconveniences in exchange for a small fee, you can make good money shopping for people. In this case you need enough cash to cover your shopping orders before people can begin trusting you with their money. Luckily, shopping for groceries is not a very expensive affair. This is actually a big business because you can do many shopping runs in a day so you can turn a good profit from your investment of $100.
