Or, should you operate at a sports goods shop, consider getting a well known athlete from the region to sign autographs for a day.
Any Ongoing Promotions: You could have special deals or occasions once weekly, once a month, maybe even once per year.

(assuming you constantly have it on a Thursday). Alternatively, you might have a signal made up with a place that is blank in order to record on the day and date.
Regardless of the occasion, make sure to utilize any signage that is bodily as well as the Internet you use. MySpace, Twitter, use Fb, a LinkedIn, everything and anything you can. Set up an Yelp account so people can afterwards write critiques of whatever you're planning, and be sure you're on FourSquare so people can "sign in" when they visit your store. Signs and banners are excellent for getting out the first word there, but you require follow up advice that folks can conserve on their computers or phones.
