This would be a website developed to allow its users to input the deals of a business they would like to have. For example, you could ask your local Pizza restaurant to sell vouchers for pizzas at 50% off. When there are enough people registered, the business will be asked to participate in the deal. So, the precise deal will come from the users, not the business itself, so a small business will benefit from this deal for sure. When a small restaurant gets about 100 deal participants saying they would want a meal for $30 instead for $50, what do you think they would do next? And maybe participating in a site-deal could cost, for example, 1 dollar/euro for the user and zero for the business.
