Starbucks Rewards Card

So I just purchased myself a Starbucks giftcard in hopes I can start earning rewards on my daily cake and coffee intake. (after 5 transactions on the card, so they tell me) So yadda yadda I register my card, found out I already have an existing Starbucks.com account, and then a little more poking around brought up the last giftcard associated with my login from June 15, 2005. I could’ve been earning rewards since 2005?!?! WHY DID I NOT REALIZE THIS… Life fail.
