I will advice newly opened small businesses to do free advertising. Especially it won't cost you anything but then will be a great help for your customers. If you have a local store, you might as well want to market your products online. To entice other customers and for them to know what you have to offer. Look for classified ads that offers free posting of classified ads. A great ad has short yet informative content, has a photo of the product or service that it has to offer. You will gain much more clients if you have your own logo/photo so that clients may recognize you and to let them know you're not a scam. Again, be responsible on your own postings, never spam a site or you'll get banned.
