Nope this was my experience too. I also heard that they'll knock 50% off or more if you offer to pay cash on the day of. This was also not true (at least in Alaska).
In Utah I've gotten further, but usually if they knock off 20% I've had a good day. It's insanity. The market is completely messed up.
My dentists always gave me 10% off for paying cash. Collection agencies often gave me 10 to 20% for paying the whole balance by credit card on the phone. Hospital sometimes gave me 25% for paying a year old balance within 1 month. These were all insurance repriced bills, except of the dental. Many bills were over 1 year old, because of billing errors and numerous back and forth between me, service provider and insurance company.
