charges into battle with Amazon armed with heavy sarcasm and sincere outrage

If you’re trying to get customer service, sarcasm isn’t the best weapon.

I've made the agent laugh twice already.

I did this stuff on his end of the phone for nearly 10 years, I know how to not point it at the person actually ON the line.

Either way, I think an order placed on June 11th with a promised delivery of August is not acceptable.

Why not?

... unless they changed it after the fact?

It wasn't a preorder.

And the "delivery estimate" has changed at least three times.

Yeah, supply chains are messy right now, and anything involving chips can be insanely difficult to source.

AND there was no suggestion on the item page at the time of order that delivery under Amazon Prime was going to take any longer than one might reasonably expect for a "heavy/bulky" item.

[hangs up] Well, that makes me feel like a much more satisfied customer at this point. On top of which, I got to tell him how the U.S. Interstate system is numbered, and we compared environments.

Hmmmm... I see your point about chips. Unfortunately, there were no advisories on delays at time of purchase.
