If you have a Starbucks gift card there are quite a few beneifts of registering it on their website:
Complimentary Beverage Customization - Purchase a beverage with your registered Starbucks Card and you can get select syrup and milk options (like soy) on the house.
Free Refills on Brewed Coffee - Your registered Starbucks Card gets you brewed or iced coffee refills at no charge.
Free Beverage with Whole Bean Purchase - Get more coffee with your coffee. When you use your registered Starbucks Card to buy 1 lb of our whole bean coffee, we'll give you any tall (12 fl oz) beverage of your choice.
Up to Two Hours Free Wi-Fi Daily - Surf while you sit in coffeehouse comfort. With your active registered Starbucks Card, you'll receive up to two hours of Wi-Fi service every day.
And now, you will also get a free beverage on your birthday when you register your card!
Needless to say...I just registered the card I've had in my purse for ages now. It has less than $3 on it, but I can always re-load it to continue to take advantage of these freebies!
(Thanks "Deal"icious Mom for the heads-up!)
