For $750 you get 5 nights in a fancy hotel condo, normally worth $500 each each night, + $180 off for avis car rental, + 5000 spg points.
How do you get those rates ?
1. Random mail from spg
2. Get a referal from an owner at the property. Send a private message (pm) to one of the owners and ask for a referal. It does not cost them anything, and if you actually end up buying, they get bonus referals.
How to ask for referals? Ask one of your friends owners, or pm these guys:
