Perfect for any type of online marketplace. Was originally used for a website I built many years ago which advertised brick and mortar sales around New Zealand. I like to think it was more successful than my only competitor at the time (salefinder.co.nz) because it advertised ALL sales, not just the sales of companies that paid to advertise. People liked having a single place to go to find out all the actual brick and mortar sales and they signed up in droves. It was a lot of work though. I have since stopped web development and it’s time to let this go to someone else. The concept will still work right now if you have the time and energy to load sales. Or use it for your own great idea!
