Bulk Hardware Bundles and Package Deals
Bundle pricing often reduces per-unit cost. Packages including latches, screws, and rosettes can drop the effective price per knob by 10–20% at higher volumes. Assumptions: standard latch assembly, dimpler screws included.
How to Compare Quotes Without Missing Details
Side-by-side quotes should show per-knob price, total price, and included hardware. Look for comparable finishes, cylinder type, and warranty terms to avoid hidden costs. Assumptions: identical scope across bidders.
Typical Add-Ons That Change the Final Price
Delivery, packaging, and packaging size affect the final bill. Freight charges for bulk orders can add $0.10–$0.50 per knob, while bulk packaging sometimes reduces breakage costs. Assumptions: standard palletized shipping.
Regional Price Variances: A Quick Map of Costs
Prices vary by market size and supplier density. Northern states with higher living costs may see per-knob prices up by 5–15% versus southeastern markets. Assumptions: standard freight within 500 miles.
