NUDEBLANC review for Gameball: AI Loyalty & Games

Have been looking for an app that helps my store to do the VIP system. I've tried like 10+ apps and most of them are not useful for me, not to mention the high price. But Gameball is literally the best app so far I've used. Reasonable price and useful function. Also their support team answer so quickly (like within half an hour?) Would definitely recommend all of you to try!
