We had the same issue where we never used the "checkbox" version of the Produce Supplies cards for the entire campaign, and by November or so they're kind of a dead draw as you likely only have 2-6 cubes in the stockpile ever, and some size 8 cities from permanent supply centers.They are useful for using "discard Player card to get a city card" type abilities, at least.
My wife an I lost our first December game with our "carrier" one move away from Johannesburg. The plague cubes just came out too fast and we had used our remaining frequency scans to mill the deck for the colors we wanted, which meant we skipped about three epidemics. This turned out to be a mistake because we went so long between epidemics that the Hollow Men gather cards were very diluted and we couldn't keep up with the supply removal with a 42 city grid and only 30 cubes.
Luckily on our second try the carrier made it to Johannesburg in only two turns. We had set up the minimal route - red-red-red-black-black-yellow-blue - and used discard fishing and radio towers to give that exact combo to the carrier.
