What's the most cost-effective approach to purchasing vertical file cabinets for a budget-constrained office?

For budget-constrained offices, the most cost-effective approach to vertical file cabinets is buying commercial-grade (not budget-grade) used units from reputable office liquidators or government surplus. A commercial-grade used 4-drawer vertical cabinet in working condition often sells for $50–150 — significantly less than a new commercial unit at $250–500. Inspect before buying: slides should operate smoothly, the lock should work with a key, the anti-tip mechanism should function, and the surface should have only cosmetic blemishes (not structural damage). Alternative: buy new entry-level commercial units from FindOfficeFurniture.com that provide commercial durability at competitive pricing — call 888-719-4960 for current pricing.
