The cheapest office supplies can often be found by shopping around among various retailers, including online marketplaces and bulk suppliers. Here are some of the best options for finding low-cost office supplies:

• eBay : Some sellers on eBay offer office supplies at prices lower than Amazon and other retailers, especially for specific items like padded envelopes. However, it may be difficult to get all your items from one seller

• Amazon : Offers a wide selection of office supplies at competitive prices, including both brand-name and budget-friendly options. It's also convenient for comparison shopping

• Walmart : Known for competitive pricing and bulk purchasing options for office supplies

• Costco and Sam's Club : Provide office supplies in bulk at discounted prices, primarily for members. Good for buying in larger quantities

• Dollar stores (e.g., Dollar Tree, Five Below) : Great for consumable office supplies if you don't require name brands, often priced under $5

• OfficeSupply.com and BulkOfficeSupply.com : Specialize in office supplies with bulk discounts and frequent deals

• Staples and Office Depot : Offer promotions, loyalty programs, and price matching guarantees which can lead to savings, especially when combined with coupons and seasonal sales

• Costco and membership clubs : Offer discounted prices on bulk office supplies for members

• Specialty discount office supply companies : For example, OfficeStationery in the UK offers discounted prices with free delivery and price matching to ensure low costs

In summary, the cheapest office supplies depend on the type and quantity you need, but eBay sellers, Amazon, Walmart, dollar stores, and bulk suppliers like Costco and BulkOfficeSupply.com are generally among the most affordable sources. Utilizing price matching, loyalty programs, coupons, and timing purchases during sales events can further reduce costs
