Walmart has launched a mail food subscription services called Goodies. It allows shoppers to have new foods mailed to their door for a monthly fee of $7.

The items can range from organic to ethnic, and they're not found on store shelves right now. The products are sample-sized. If a customer like what they get, they can order full-sized products online.

Walmart started testing the service three months ago. So far, it has about 3,000 subscribers.
