If you are following ntrdx's guide, you really only need to spend 20 kills on 3 repellents once, once you are down to 1 repellent, you can purposely die and restart the level, you will keep all previous kills and start with 3 repellents. You can repeat this until you have the desired amount of kills to purchase good weapons and armor, Because the higher the level, the higher amount of zombies.
