Holy carp but I am shocked that I did not see this.
I suspect someone is gonna make a boatload of cash @ $1. a round.
People will buy this carp.
Heck I would if I could get past the $1. a round part.
I did notice that on all pages it says

You must be at least 21 years of age to purchase Handgun or Rimfire Ammunition.

If this is the case and I was underage, I'd buy some rifle ammo.
They may have typo'd tho.
