So everyone tells you that the only way to get ahead in business is to advertise. Well, that's true, but you need to make sure that you stick to inexpensive advertising methods when you're starting out. Spending hundreds of dollars for an ad in the local newspaper might turn out to get you very few new customers, and you will have spent your entire advertising budget on it.
Make your money go further with leaflets, direct mail or email -- these are easily targetable campaign methods with high response rates and low costs. Remember that it is always better to spend money on an offer than on an ad, and always better to spend money on an ad than on a delivery method.
