We received an email today from our realtor/condo manager about possible collusion between travel sites and booking sites aimed at fees from those wh rent out their homes. There is an explanation and a petition you can sign to try to get U.S. to open an investigation. It is easier for you to read it than for me to try to explain it.

i did forward this to my son's girlfriend who is a researcher for a firm that specializes in collusion cases who will forward it to her boss. I don't know if anything will come of it but you never know.
