If you are needing to buy storage boxes, the type of box you need will help determine where you should look. Are you needing moving boxes, or boxes for home storage? Do you want decorative storage boxes? Or do you need plain cardboard? Would you prefer wooden or plastic boxes? These are all questions to think about before you begin your search.
For moving boxes, moving companies such as U-Haul are a good place to look. They sell sets of boxes in varying sizes and prices to accommodate different types of moves. If you are just moving to or from a dorm room, you will need far fewer boxes than if you were moving the contents of an entire house. Look at different moving companies to see which offers the best deals on their box sets. There is also the option of finding used boxes online. Some sites specifically deal in used cardboard storage boxes, but Craigslist and other similar sites are also good places to check. You can even place an ad yourself on one of these sites, saying you are willing to take any unused boxes in good condition. Offering a small fee for a large number of boxes might be a good idea.
For home storage, large-name retailers are the best places to buy. If you have a store in your area that deals specifically with home organization needs, such as The Container Store, they will likely have a huge selection of storage boxes to choose from. Plastic storage boxes especially are well-represented at such stores. Stores that are more tailored to home furnishings, like Ikea, will have a variety of decorative boxes to suit your home’s decor. These stores may sometimes have a wider selection of nice boxes online, so be sure to check both the websites and the actual brick-and-mortar stores to find exactly what you are looking for.
