I contacted the company and here is their response:
"Hello,
Thank you for taking the time to contact us by email regarding a survey invitation that you had received. This person is not affiliated with Ipsos, and the email you received is not a legitimate offer.
We are sorry for the bad experience that you have had, and we would like to continue to investigate this matter. We take great pride in our work and our reputation for sound business practices, so we appreciate you reporting this incident to us.
Thank you for your understanding.
Best regards,
Judith

Yep - we were correct. If a company paid $180 for a single shop everyone would be doing it!
