I have signed up for it every year for more than a decade. I only had a bad experience once, the first time I did it, and even then, a volunteer gifter stepped up and made it right. I wonder if that timing is not a coincidence, but a hidden algorithm that pairs first time users together, since they are the highest risk of not following through. I assume if user does not send a gift, they are ineligible for getting a replacement gifter.
