The coupon contained this notice:
For several years now, we've invited shareholders to visit their favorite Starbucks by including a Starbucks Card in out annual shareholder mailings. We viewed it as a good way to introduce this innovative Card program to our investors. Over the years, the Starbucks Card has become an old favorite with our shareholders, thanks to the experiences they've enjoyed as they used it to visit their Starbucks.
This year, we'd like to offer you a new kind of invitation - one that will allow you to share the exceptional coffee and warm hospitality you enjoy at your Starbucks. So get together with someone you care about and drop in for coffee. Our treat. Then visit us online at www.mystarbucksstory.com to tell us how you used this invitation to share your Starbucks with a friend.

I will continue to use my shareholder card from 2006:
I liked the design better than the one from 2007:
