It's been 10 days. It would be good if we could get some more information about your retail store so that the people here can share some strategies that may be able to help you out. I'm expecting some people replying with things like these:
You should get a lot of real people to follow your Twitter account
You have to be honest; this is a really hard thing to do, especially if you're someone new in the business. It's not impossible, but the possibilities of that happening aren't really as high as you being able to get a tail in a coin toss.
You should interact with ALL the people who are mentioning you
I follow Twitter celebrities like WWE's Zack Ryder, and I'm not really expecting him to reply to me, retweet any of my messages, or add any of my Tweets to his favorites because of the huge amount of followers that he has. Again, that isn't impossible (double negative, lol), but the chances are not high. Imagine trying to get Emma Stone's attention on Twitter and get her to reply to you.
