I was browsing StarbucksStore.com and found Burundi Gitaba. I actually had to search for it. The email from StarbucksStore.com mentioned this coffee, yet when I browsed the Reserve coffee listing, I didn't see it. I went to StarbucksStore.com just now, and used the search function and typed in Burundi and found this:
I managed to order one bag. The page I ordered it from appeared as a broken link moments later. We will see if my one bag ever arrives.
Nonetheless, Burundi Gitaba card seems to really exist. I'm counting this one as StarbucksStore.com only since I've never seen this coffee at the Roastery.
