I just pick a case, one of the first 4 and then I let it run a little bit. Today I got 10 & 15 AM. I try to pick different colour cases each day. But no idea what works or not!
I also got that Shell offer but I already have the app so useless to me. And a Heelie one, well two actually. I'd like to get a Metro offer if I don't just get straight miles
