Quick question about the referral program, especially with overlapping periods this round. 1) how exactly does it work? If I get 3 referrals, do I only get the Powerwall currently, or do I get for items 1, 2, and 3 as they are achieved? Mainly, 2 referrals don't matter to me, the solar roof token means nothing to me. But I'd love the kids car, and a powerwall. So id rather stay at 1 than go to 2 without assuring 3. 2) typically when do prizes get paid out? Only after the program is over, or as they are achieved ? 3) what referral prizes do you want to see in the future? I feel some of the prizes don't really match the achievement. Invite to semi-truck event after 5 referrals, on my dime? I love Tesla but I'll take the powerwall and watch online any day.
