Follow up on <$2.20 gas process:
I went again to use Giant/Shell in NOVA. It worked a little bit differently this time so next time I will try at the pump.
1. Go inside ask for the pump to turn on; 2. Pump gas; 3. Go inside and enter rewards info; 4. It says I have $2.09 rewards (original price $2.099); 5. Swipe credit card, 6. Paid $0.35 for 35 gallons; 7. Giant deducts 2200 gas points, 8. Giant credits 110 gas points back a couple days later.
This Shell had a new payment terminal that would accept NFC payments and chip.
