For the past month or so I've started up a new business and have been unsuccessful. I've joined a group as a merchant so I can advertise via notices twice a week, but that has been unsuccessful. I'm renting a small shop, where I have made no sales, even though all my advertisement in the aforementioned group has been lead here. I've got a Marketplace shop, which has also had no sales. What do you think I should do?????? P.S. Don't be afraid of giving constructive critism of my products (https://marketplace.secondlife.com/stores/47539)
