what's wrong with this deal?

Emily Helwig Good morning, you could verify this penalty, please. When I invalidate this offer, it was still in "Green" and still had the option to be validated here in Dealspotr, however on its website the coupon did not work because it had already expired or maybe it was invalid, but still I was penalized. Why ?
