I don’t know about the others but I just contacted Autozone and was told they don’t advertise on Rushs’ show.
Here is the response from Autozone:
Dear valued customer:
Thank you for contacting AutoZone regarding your advertising concerns. AutoZone does not purchase advertising on Rush Limbaugh websites, or sponsor the Rush Limbaugh radio show.
If a commercial did run, it was an error. Again, thank you for taking the time to contact us. We value your comments and appreciate you as a customer.
Respectfully,
