Can I promote the business before the grand opening?

[imisidro]

OF COURSE

Even on the Web, some websites are already up just to announce that the business is coming soon. Look at examples of coming soon pages - you may get some ideas and put it up while the site is still being designed and created

In the meantime, you can already start your social marketing to drum up excitement about the business.

As for the shop itself, I suppose that you have banners announcing the opening of the new business. Start checking the rates of your local newspapers and see if you want to get ads to announce the opening.

You can do a lot of local marketing. On the Web, create your Google Places page already http://www.google.com/places . Check the source below for more local marketing tips
