very interesting idea, in this modern world an idea can change your way. so coin rebate program has brought to us a fantastic platform for shopping purpose. Normally I like shopping at the Walmart store. so that if I would like to join this system then how can myself engaged with this platform. I love this idea. yeah, one interesting matter is that I and my team are going to launch a token card system for the food purchasing matter. so it is almost a similar project.
