...participants were asked to choose one of the following:
A free Hershey’s Kiss
A $0.13 Lindt truffle (a superior product in quality that retails for multiples more than a Hershey’s Kiss)
Well obviously, I'm getting a free thing as a no-brainer, and then I also decide whether I want the paid thing or not.
They seem to be oblivious to transaction costs. What if they offered free candy after the e-mail confirmation, but the paid truffle no strings attached?
