Guardians of Harmony originally released as an Amazon exclusive for most of the main set. It was the only truly reliable way to get them outside for re-sellers. As of today, they are now available at stores like Walmart. This includes pretty much everything at our Amazon listing post (which you can still order from with discounts)
Be sure to call in first first, but we've received 5 reports now, so you should be good!
