Gold Tier (500–2,499 Stars): Once you hit the 500-Star threshold, your earning rate jumps to 1.5 Stars per $1 (correction: 1.5 in Canada and 1.2 in the US). Reserve Tier (2,500+ Stars): The elite level offers the highest rate at 1.7 Stars per $1. While Green tier Stars still expire after 6 months, you can now extend their life by another month simply by making a purchase or reloading your card. For Gold and Reserve members, the expiration timer is removed entirely.
