Check with local retailers: Most retailers receive shipments in cardboard boxes and are usually willing to give them away for free. Call or visit stores like Walmart, Target, Hobby Lobby, Michaels, Jo-Ann, or Utrecht to ask if they have any boxes available.
Visit recycling centers: Recycling centers are a great place to find free cardboard boxes. Check with your local recycling center to see if they have any boxes available.
Ask friends and family: Your friends, family, and neighbors may have extra cardboard boxes lying around. Reach out to them and ask if they have any boxes you can use.
Check online: Websites and mobile apps like Craigslist, Freecycle Network, Facebook Marketplace, and OfferUp have a "free" section where people give away items they no longer need, including cardboard boxes. You can also join an online Freecycle group and post about how many free moving boxes you need.
Check with schools and offices: Schools and offices often receive deliveries in cardboard boxes and may have extra boxes available. Talk to your co-workers or school staff to see if they have any boxes you can use.
