In a surprise, the Walmart exclusive LEGO Classic 60th Anniversary Truck (4000030) is now available for purchase on Walmart.com. The reason for the surprise is that it is now available at 12am EST which is about twelve hours before the other sets were released on their respective dates. Like with the previous anniversary sets, this one will also go for $19.97 each and you can either have it shipped to your location or you can pick it up at your preferred store. You can also combine it with the LEGO Classic Bricks on a Roll (10715) set to get over the free shipping threshold. This is the last of the Walmart LEGO 60th Anniversary series of sets that will be available.
Thanks to Ben for the heads up.
