@Crabbers no handles though! I had Uline ship me a bundle of those exact boxes and after filling one up just now, I am definitely thinking its too heavy
Grocery Store Fruit Boxes and Liquor Store Booze Boxes. Give them the heads up that you are looking for them and see if they can set them aside for you. They're free, sturdy and lots of times have handles. Good luck on the move!
