No question about the cost savings from changing the $1 and $2 bills, however vending machine operators ultimately benefitted from this.
Instead of raising the price of an item from , say, 85 cents to 95 cents, prices quickly approached $1. The consumer was screwed.
And if vending machines could be changed to accept Loonies and Twoonies, couldn't they have been changed to accept $1 & $2 bills?
As someone who ends up with tons of change everyday, I think changing the $1 bill (but not the $2 bill) was a mistake. The Americans seem to be doing alright with their $1 bill. JMHO.
A couple of points. The cost to accept notes is much higher than machines that accept coin. It is only recently that such mechanisms have become available, and each time a note is fundamently changed, the scanner inside needs to be programmed to accept both the old note and the new note. Casinos, with their high mark up, can well afford to change things.
In 1987, when the loon came out, there was no method of accepting $1 notes in vending machines, and little progress was made until after the release of the $2 coin in 1996.
For those that find the prices went up when the machines switched to loons and $2, it would have gone up a lot more had the technology been available to accept low denomination notes. It is all a matter of the cost to accept certain payment, which is simply charged back to the customer.
I note that when the new $20 came in last year, the casinos had the mechanism in place to accept them immediately, which lead me to believe it is possible that test notes were issued prior to the introduction of notes to the general public.
