Welcome to WebmasterWorld Hajira
People don't like being sold to, especially in social media, but they do accept advertising. Don't think about promoting the products unless you are planning on advertising on twitter.
Use your profile on twitter to interact with others, strike up conversations, and discuss topics of interest. Your profile is your shop window and if you're engaging, people will naturally be curious.
