I have been using Shopkick for about a week. I have gotten to 4811 kickbucks, but for the last two days it has stopped giving me my referral bonus. I am owed for at least 20 people. I have tried to email them, but no answers. It really sucks because I loved this app. Btw, no I haven't been using it with fake scans or anything. It still gives me check in points and scan points, just not referral kickbucks.
