You’ll get a letter in the mail about the bean stock once a year as you continue to work for starbucks, as for adding to the bean stock yourself i’m not very sure, so you should call partner contact center 1-866-504-7368 . So once you call you can ask away all questions about anything and if that’s not the right number for what your inquiring about they’ll guide you to the right number! For the 401k you’ll also occasionally get a post card type of thing in the mail if you qualify for it, the most I know about the 401k is that you have to be 18 and they match a certain percentage of what you put in it each month, so say it’s 100$ a month you put in they’ll match a certain percent of that and add to the 100$.
