Hi,
I have seen it sold in our local grocery stores. If you have Albertsons where you live, they'll have it. It's not where the bottled spices are. It's usually in a plastic bag with all the other spices that are in plastic bags. Like someone said, it is shaped just like a star and has a reddish-brown color. It is also popular in Chinese cooking, as well as Indian cooking so oriental food and indian food stores should have them too.
