I have earned the most sats from SN and my shakepay visa card. I think in the past 15 months from all sources of "earning" sats I am close to 1M sats. That's not a bad start for low income people who struggle to afford stacking. I could earn a lot more as well that is just basic rewards from picking up a few things at the grocery store, pharmacy and home depot here and there and paying with my shakepay card. My wife does the bulk of the family shopping, we would earn a ton more if she was using the shakepay card.
