The website states: "Match my PLATINUM membership in Nordic Choice Club with Hertz Gold Plus Rewards - President Circle."
This offer, therefore, appears of limited use (to be honest, I had never even heard of the Nordic Choice Club, let alone their platinum membership).
I had never heard of Nordic either. All I did was fill in that forms and hertz matched me. Hertz clearly did no investigative work. There are lots of DP's on Reddit as well.
