Let me summarize. The 2 methods.

1. Have customers who come back frequently and spend money. 2. Have a lot of new customers who spend money. They tell there friends to come, and spend money. Rinse. Repeat.

2. do not have advertising expenditures at all.

One caveat to the article is that it is not in every business's long term interest to grow quickly.
