I wonder what a removal of “bulk rate” would do to the system?
We’re already being advertised at from every direction. A reduction in physical advertisements that end up in landfills would be a good thing.
Then the advertisers would have to decide if paying the full rate would be worth it to get their message out.
And the post office would se a jump in revenue if they decided to, and a drop if they didn’t, but the amount of time and energy spent sorting and delivering that crap – as @Snork said above – may balance it, and make the system more efficient.
It won’t happen, but I’m enjoying the thought.
