Well, since you wont accept what they say on Shidoobee or IORR, I'm not sure what answer you will find acceptable for now.
But, yeah, you just have to wait...they are not going to magically stop selling VIP/platinum tkts and all of the sudden thousands of standard tkts appear...
Thats just not a thing....never has been.
The Platinum sales go thru the end...that operates on an algorithm...not by a human who watches every seat.
Unsold VIP tkts tickets will stop about 2 weeks before the show as they need firm numbers for the hotels, the crappy "gifts", shuttle busses etc.
They then dole out the rest to the Lucky Dippers...
Any leftovers then go up for grabs....about a week before each shows...
I believe all this was already explained a few pages ago when you first asked. Vivid seats and StubHub are good sources for late sales....I always score great seats for shows and hockey games
from each...usually on day of, you can find below face value after lunch time.
And yes, they are very reputable.
When Buffalo cancelled a few years back...I had my money for my GA ticket refunded to me within 3 days, if I recall.
No questions asked.
