The new LEGO 71012 Disney LEGO Collectable Series Minifigures is now sold out at the LEGO Shop at Home (USA | Canada). They were sold out midday on the initial date of release on May 1st, 2016. Your best bet now is to check your local stores for availability.
For those living in Europe, LEGO Shop at Home UK still has them instock at £2.49 each. However, they probably won’t last too long over there so if you haven’t ordered yours yet, you should soon!
