Wal-Mart stores in America are now carrying the new Summer 2015 LEGO Star Wars sets. They are not available online yet.
For those living in Canada, the new LEGO Star Wars sets along with Marvel Ant-Man Final Battle are available online and in-stores. The new LEGO UCS Helicarrier is available at Walmart.ca now too which means it is no longer exclusive to only LEGO Brand Stores/Shop at Home.
Thanks to forum members AbuTaleb and zmw92 for the heads up!
