Popsugar Parenting Kid Activities Harry Potter Lego Build at Barnes and Noble August 2018 Important PSA: You Can Build Harry Potter Legos For Free at Barnes & Noble This Weekend 31 July 2018 by Alessia Santoro Image Source: Flickr user Mike Kalasnick As POPSUGAR editors, we independently select and write about stuff we love and think you'll like too.

In honour of Harry Potter and the Sorcerer's Stone's 20th anniversary and shortly after the news of the newest Harry Potter Lego sets of the year — including that viral, enormous Hogwarts Castle set — Barnes & Noble is hosting an event that'll make you want to cancel your weekend plans pronto. At 2 p.m. local time on Aug. 4 in select B&N stores, you and your kids can build mini Hogwarts Expresses with Legos, which you can then take home! Sign. Us. Up. Although there will be limited availability in each store hosting the event, many locations are accepting sign-ups in advance, so call your local store ASAP to see if you can slot yourself on its list beforehand. You need not worry if you can't get in there quickly enough to build the mini Hogwarts Express, though, as the bookstore is offering a few other in-store opportunities that are worth showing up for. In the spirit of the first book's 20th birthday, all paperback versions of the series will be 25 percent off, including the newest editions featuring artist Brian Selznick's incredible artwork. Additionally, all of the new Harry Potter and Fantastic Beasts Lego sets that are currently for sale will be available for purchase at the event. New Harry Potter books and themed Legos? Sounds like the perfect Saturday to us. Check out the Lego sets and books you can find at B&N this weekend ahead!
