Banker boxes are sold at office supply stores, warehouse clubs, and online retailers, with prices ranging from $1 to $3 per box depending on quantity and where you shop

A banker box (also called a storage box or file box) is a cardboard container designed to hold documents, files, or general storage items. The most common size is 10" × 12" × 15", which holds about 2,000 sheets of paper. You can find them at nearly every major retailer that stocks office supplies, and the choice between where to buy depends on how many you need and how quickly you need them.

If you need just a few boxes, a local office supply store or big-box retailer will have them in stock today. If you need dozens or hundreds, buying in bulk online or through a warehouse club saves money per box. The trade-off is shipping time or membership fees.

Key Takeaways

  • Staples, Office Depot, and local office supply stores stock banker boxes year-round and let you buy single boxes without shipping costs.
  • Costco and Sam's Club sell banker boxes in bulk packs at lower per-unit prices, but require membership and may have limited selection.
  • Amazon, Uline, and Grainger offer bulk ordering with delivery to your home or office, useful when you need 20 or more boxes.
  • Prices per box drop significantly when you buy in bulk—single boxes cost $2 to $3, but bulk packs of 25 or more average $1 to $1.50 per box.
  • Local moving companies and storage facilities sometimes sell boxes at competitive prices and can advise on size for your specific need.

Office Supply Chains: Staples, Office Depot, and Local Stores

Staples and Office Depot both stock banker boxes in multiple sizes and carry them year-round. You can walk in, buy one box or a small pack, and leave the same day. Prices at these retailers are typically $2 to $3 per box when bought individually or in small quantities (packs of 4 to 10). Both stores also offer online ordering with in-store pickup, which is useful if you want to avoid shipping costs but prefer to order from home.

Local independent office supply stores often have banker boxes in stock and may offer competitive pricing, especially if you buy in volume. Call ahead to confirm they have the size you need—smaller stores may not stock all dimensions. These stores sometimes offer discounts for repeat customers or bulk purchases, and staff can usually recommend the right box size for your project.

Warehouse Clubs: Costco and Sam's Club

Costco and Sam's Club sell banker boxes in bulk packs, typically 25 to 40 boxes per case, at prices between $0.80 and $1.50 per box. This is the lowest per-unit cost if you need a moderate quantity. Both clubs require an active membership, which costs $60 to $130 per year depending on membership tier. If you already have a membership, this is often the cheapest route.

The downside is selection and availability. Warehouse clubs rotate inventory seasonally, so banker boxes may not be in stock year-round. Call your local warehouse or check their website before making a trip. If you need boxes outside their stocking season, you will need to use another source.

Online Retailers: Amazon, Uline, and Grainger

Amazon carries multiple brands of banker boxes with delivery in 1 to 2 days if you have Prime membership, or standard shipping in 5 to 7 days. Prices range from $1.50 to $2.50 per box depending on brand and pack size. Amazon is useful when you need boxes quickly and do not have a warehouse club membership or nearby office supply store.

Uline and Grainger are wholesale suppliers that cater to businesses but sell to individuals. Both offer bulk pricing on cases of 25 or more boxes, with per-unit costs as low as $0.90 to $1.20. Shipping is usually $10 to $25 per order, so bulk purchases make the most sense. Delivery typically takes 3 to 5 business days. These sites are best for orders of 50 or more boxes where the bulk discount outweighs the shipping cost.

Moving Companies and Storage Facilities

Local moving companies and self-storage facilities often sell banker boxes to customers who are packing or storing items. Prices are usually competitive with office supply stores ($1.50 to $2.50 per box), and staff can advise on which size works best for your contents. Some facilities offer discounts if you rent a unit from them. This option works well if you are already working with a moving company or storage provider.

Call ahead to confirm they have boxes in stock and ask about bulk discounts. Some smaller facilities may only stock a limited quantity, so ordering in advance is wise if you need more than 10 boxes.

Comparing Price and Convenience

The best choice depends on how many boxes you need and how soon. If you need 1 to 10 boxes today, go to Staples or Office Depot. If you need 20 to 50 boxes and have a warehouse membership, Costco or Sam's Club is cheapest. If you need 50 or more boxes and can wait a few days, Uline or Grainger offers the lowest per-unit cost. Amazon splits the difference—faster than wholesale suppliers but more expensive per box.

Here is how the main sources stack up: Staples and Office Depot charge $2.50 to $3.00 per single box but drop to $1.50 to $2.00 in small bulk packs. Costco and Sam's Club require bulk purchases (25 or more) at $0.80 to $1.50 per box but are seasonal. Amazon runs $2.00 to $2.50 per box with fast shipping. Uline and Grainger offer the lowest bulk prices ($0.90 to $1.20 per box for 50+) but charge shipping and take 3 to 5 days. Moving companies and storage facilities typically match office supply pricing and provide informed information on sizing.

Choosing the Right Box Size

Banker boxes come in several standard sizes. The most common is 10" × 12" × 15", which holds about 2,000 sheets of paper or 30 to 40 pounds of mixed items. Smaller boxes (9" × 12" × 10") hold about 1,000 sheets and are easier to carry. Larger boxes (12" × 15" × 10") hold more but become heavy when full. Most retailers stock the standard 10" × 12" × 15" size; if you need a different dimension, check the retailer's website before buying.

Consider what you are storing. Heavy items like books or files need smaller boxes to keep weight manageable. Lighter items like documents or office supplies can go in larger boxes. If you are unsure, the standard size is the safest choice because it is stocked everywhere and works for most storage and moving tasks.

Frequently Asked Questions

Can I buy a single banker box, or do I have to buy a pack?

Staples and Office Depot sell single boxes and small packs of 4 to 10. Warehouse clubs and online wholesalers require bulk purchases (usually 25 or more). If you need just one or two boxes, a local office supply store is your fastest option.

Are banker boxes recyclable or reusable?

Yes. Banker boxes are made of cardboard and can be recycled through standard curbside programs or taken to a recycling center. Many people reuse them for storage or moving multiple times before recycling. Some retailers accept used boxes for recycling if you bring them back.

What is the difference between a banker box and a regular cardboard box?

Banker boxes are designed specifically for file storage with reinforced bottoms and lids that fold down securely. Regular cardboard boxes are less sturdy and not designed for stacking heavy files. Banker boxes cost slightly more but last longer and protect contents better during storage or moving.

Do I need to assemble banker boxes, or do they come ready to use?

Most banker boxes come flat and require assembly—you fold the bottom flaps, fill the box, and fold the lid down. Assembly takes about 30 seconds per box. Some retailers sell pre-assembled boxes at a higher price, but this is rare and usually only available through specialty suppliers.

What if I need boxes urgently and my local stores are out of stock?

Amazon with Prime membership delivers in 1 to 2 days. If you do not have Prime, call nearby moving companies or storage facilities—they often have boxes in stock and can sell you a small quantity the same day. Uline and Grainger offer next-business-day delivery on some orders if you place them before their cutoff time.
