it occurs to me to really obscure my exploitation of this system

I should hit the ATM and start paying in cash when I go on my runs to exploit a sale. Be strategically intelligent. I have 3 smartphones too that could all get their own card to make a 20 item limit out of a 5. Have to be careful so we still get enough fuel points to fill but this is what happens when you irritate me so much I'm out freezing in the cold to figure out you started trying to figure out which accounts belonged to which households. Now I'm bent on doing it to humiliate the clever soul who tried to stop me from playing these kinds of games against them.
