A few of us started some talk towards a PS Buyers Group. We even discussed liability (as Cda Post holds the account holder responsible for unpaid accounts).
I think if the effort is being made to negotiate a discount with a carrier, it wouldnt take much more effort to negotiate discounts for everything including shipping supplies, hotels, airfare etc etc.
Maybe a new Thread could be started with people interested in participating expressing their interest. It would take some energy to kick it off but the final efforts could result in big pay backs in reducing our operating costs.
I even suggested incorporating a "Buyers Group" and selling 25 shares at $1 per share for anyone wanting to join. In that way, no individual account holder, say with CP would be held liable for the debts of any other.
I used to deal with Buying Groups in the food industry when I was in finance with a large paper mill. Essentially, the Buyers Group holds the contract and we are all members of the buyers group (those who 'buy in').
Food for thought!
