Thanks for the report. That's no "secret shopper" assignment. It's a pure ripoff of whoever buys the gift cards and sends the photos to the email address.
If the check was sent by USPS mail, give the envelope, check, and other contents to your local postmaster to be turned over to the postal inspector.
