For the moving questions, customer service told me that if a package is deemed undeliverable by UPS, it is sent back and points are refunded. However, most likely it'll just be delivered to a neighbor or something. In my case, I wasn't home yesterday and UPS arrived, but the package was left at the leasing office. Just make arrangements beforehand.
As for the raffle system, it's just like it sounds. Instead of getting points for guaranteed products, you use points to enter raffles for products. It was mentioned in a user survey that popped up on some accounts.
