If you haven't done this yet, today (3/14) is the last day.
You must be a new member to Starbucks Rewards for this offer.
Do you have a Starbucks Gift Card? If not, you have time to buy one (or download their app, create an account and get a digital card)! You can sign up and register your gift card through 3/14, and Starbucks will put an additional $5 on that card! You can read more info and sign up here.
Wow, this was super simple. I had a Starbucks Gift Card sitting in my wallet with 17¢ on it for about a year. I just registered it and signed up. Within a minute, my new balance was $5.17! It may take up to 24 hours though to receive your credit.
A few notes: Jess commented that she used the ecard from the Blonde Roast promotion and she was able to register that and get $5 added to it!
Ruthanne also said on Facebook that they give free same visit refills on iced-tea or iced or hot coffee if your card is registered! Sweet!
