Yep,
A family member went to have back xrays a couple weeks ago. There was a question whether her insurance would cover it and I chose to pay cash. The receptionist gave me the cash price and I asked if that was discounted for cash and the answer was yes.
I think there were four xrays on two location of back.

I went to a chiropractor a short time ago and I chose cash option in lieu of insurance. Charged me $25.00 for a call that would normally run 35 to 45 under insurance.

Four xrays plus put on a take out disc. $80.00
