Barnes & Noble will open a new bookstore in Commack on Wednesday, two years after closing a shop less than two miles away. The new store, at Veterans Memorial Plaza, 58 Veterans Memorial Highway, will occupy the former Party City space near Michaels. Commack is one of two Barnes & Noble stores opening on Wednesday, alongside a new location in Livingston, New Jersey. “We are very pleased to open this beautiful new Barnes & Noble in Commack, one of two new bookstores we open today,” Barnes & Noble CEO James Daunt said in a statement. Barnes & Noble Premium and Rewards members will earn double stamps on purchases made at the Commack store from Aug. 5 through Aug. 9.
