Instead of offering a free lawn mowing on its own you have X Trend Premium Review offer a free one when they purchase a 1 month agreement, so now instead of just getting a $20 sale you just got an $80 sale for the months contract. On the same page you may offer them an even bigger offer like I suggested above like 12 months for the price of 8.
The power of this strategy is that you are building a list of prospects you can easily send emails to which are completely free. You can build trust, get them to like you which will result in more sales, as this list builds you won't even have to use traditional marketing any more. Another huge benefit is that you are increasing the size of you sale, increasing cash flow, etc.
If you're working online, I'd be willing to bet almost all of your business data is stored on your computer. Websites, accounting information, password and login details, etc. - all the stuff that you've spent a lot of time and effort building. What would you do if your hard drive crashed tomorrow? Do you have a backup of all that information or would you find yourself having to start all over again.
