ya they just manufacture paper now.
there is no "this is better than that for the entire country" it varies by region, Bank of America might use Brinks here and Garda up North, whatever, its all about regional carrier pricing, etc.
Volume is King is the only rule that holds....I've had dry spells and hot spells with EVERY carrier.....the only thing that matters is do as much as you can everyday and you WILL find silver.
