As you may recall, earlier this year, Fisher-Price released details for their new line as part of the DC Super Friends Imaginext line called Slammers. You can view a demonstration of how the packs open by checking out the video in our original post. The first wave features six variations of Batman and three variations of each Joker and Mr. Freeze. Each pack also features a matching vehicle with each figure. These have now become available for preorder in two different forms through Entertainment Earth. You can purchase either a group of three packs for $24.99 or a full case of twelve for $96.99. Both are expected to ship this month.
