Just bought a box bulk of Lego pieces at Toys R Us for 90% off. It's just a bunch of different pieces, not from specific sets. Employee said it's from February 2017 event? I guess it's from those kids event they host every month or so. I have no idea what price to list them at. they are 18 and 14 pounds of legos.
